Cantonese sausage noodles

Guangdong intestinal noodles, is pulled intestinal noodles, is a kind of application of sticky rice flour made of China's Guangdong food, to Bra into the called Bra intestinal noodles, there is no Bra free pull intestinal noodles, but not as thin as the Bra. Guangdong sausage noodles were developed by Guangzhou Xiguan Pantang He Xian Hall in the 1930s and 1940s. Guangdong intestine noodles traditional style to meat dregs, fish, fresh fresh shrimp as the filling, but also Guangzhou City, Hong Kong hotels are common small snacks, generally common to fresh shrimp Cantonese intestine noodles, beef and mutton Cantonese intestine noodles and barbecued pork Cantonese intestine noodles these. However, there are also some restaurants that do not have any fillings at all, but add sweet sauce and sesame oil to the noodles, and sprinkle them with white sesame seeds. These are the typical types of Cantonese noodles that are sold in small stores on the street.

Fish Balls

Fish balls or shrimp balls are a common snack food in the waterfront, made from fish and tapioca starch, mostly in the shape of a ball, but also in other shapes, such as a square. Guangdong Province and Hong Kong are called fish balls, and Hong Kong food stores generally create fish balls.

These fish balls (that is, shrimp balls) are fried, orange-colored on the surface, and made from the more cost-effective shark meat. They are usually sold on bamboo skewers, and are also served in disposable cups. The price per skewer/cup in the snack stall is not certain, but it seems to be in the city where the food stall is located (about 4 to 10 yuan per skewer/cup, with about 6 pieces). There is a part of the snack stall specializing in the sale of fish eggs, similar to the hot dog sausage stalls in Western countries. They are often eaten with spicy or sweet sauce. In general, there are two types of fish eggs to choose from: sweet fish eggs are usually soaked in curry sauce or satay sauce to warm them up, while the original fish eggs are soaked in white soup to warm them up.

2. Street-side shark's fin: one of the most popular street snacks in Hong Kong, previously sold by small vendors on the street, known for being served on small plates.


Rumor has it that in the beginning, some hawkers sold leftovers to restaurants for the lower class, and it so happened that sometimes there would be some uneaten shark's fin soup, in which there might be some scattered dried abalone (alias "shark's fin"), and the lower class, who had no chance to touch it, would love it and it became a popular dish. There is a little bit of dried abalone, but the taste of Qie also looks similar. When eating, white pepper, zhejiang vinegar and sesame oil are usually added. In Hong Kong, vendors generally sell more than one stall, along with shark's fin and pangolin bone soup with greens, and many people mix the two kinds of snacks together, which is not specific and very different.

Since 1990, the number of Hong Kong style cafes selling bakery buns has slowly decreased, so only the old style Hong Kong style cafes now have their own baked eggs, while other Hong Kong style cafes buy their eggs from toast bakery. The majority of bakeries will supply eggplant.


It has the aroma of a birthday cake, and the middle is half-air, so it tastes especially tender when you bite into it, with a burnt exterior and a soft interior. China and Taiwan have a similar food category called chicken cake.

How to make it: Stir raw eggs, sugar, wheat flour, light milk, etc. into egg batter and pour it in the middle of two specially made honeycomb-shaped iron templates, which are traditionally placed on top of a charcoal fire and baked out, but in recent years, most of them will be changed to a heating oven for cost reduction and safety.

Che Chai Noodles is a cheap noodle dish in Hong Kong.

It took place in the 1950s, a time when the living standard of the Hong Kong people was low. Chinese expatriates came to Hong Kong, and it was difficult to make ends meet, so there were mobile hawkers on the streets of Hong Kong, most of whom set up noodle stalls selling curry sauce and fish eggs and noodles in a kind of cooked dish. The timber carts in which the noodles were sold were equipped with metal "cooking compartments", each with a sauce, fresh noodles and toppings, and consumers were free to choose fresh noodles, toppings and sauce, generally for more than ten dollars.

Along with the improvement of living standards and hygiene requirements, the sale of cooked food on the street gradually faded. Che Chai noodles have entered Hong Kong style cafes and canteens, becoming a menu item, and there are small and medium sized stores selling Che Chai noodles, and even those going "high end".

History time

Fried chestnuts were called "filling sugar fragrance" by ancient people, and there is a poem: "Heap plate of chestnuts fried deep yellow, the guests arrive to talk and ask for wine to taste, the cold fire three nights light half stub, the door shouted 'filling sugar fragrance'. According to the History of Liao, there were professional chestnut gardens and staffs to cook fried chestnuts as early as the imperial family of Liao Dynasty (916-1125).

Production method

Chestnuts in a small black wok are stir-fried with black sand left and right with a long shovel, and the chestnuts are rolled in the black sand pile and subsequently sprinkled with white sugar. The chestnuts are stir-fried to perfection, then stirred out with an iron sieve and the black sand is sifted away. Nowadays there are some businesses that use professional equipment to fry chestnuts.

It is a concentration of chestnuts in northern China, such as Qianxi and Zunhua in Hebei Province and Jixian in Tianjin, where suppliers from all over the country gather to recycle chestnuts locally and then import and export them from Tianjin. After the chestnuts were imported to Japan, the fried chestnuts were also called Tianjin sweet chestnuts in Japan.

In addition, chestnut vendors are also common in Hong Kong.

Hairline receding? How to save h...

1、Oral medication

Androgens cause the hair follicles to shrink and the hair will not grow back, which is why they are bald. If not exposed 髮線後移 to the action of 5 reductase, testosterone will not be transformed into the hyperandrogen dihydrotestosterone, thus enhancing its ability to destroy hair follicles.

Finasteride oral medication is specifically designed to inhibit 5 alpha-reductase. It reduces the activity of 5α-reductase and the production of dihydrotestosterone. By controlling the number of bad guys who abuse the hair follicles, the follicles are safe.

Special Note: This drug is suitable for men. Women need to talk to their doctor before using it. It should not be used during pregnancy. Women also have their own medication: spironolactone or cyproterone.

Spironolactone not only reduces androgen production. It also reduces the chance of androgens doing something by pre-occupying the androgen receptors. This reduces androgen damage to hair follicles. Cipro progesterone is also a drug that can reduce the level of androgens in women.

2. Topical medication

Treatment should be early, hair follicle atrophy can also be treated if the hair follicles die, but what drugs are ineffective.

The course of treatment is long, the effect of drug treatment alopecia is slow, usually need more than a year of continuous medication. Many patients are too troublesome, think the effect is not obvious, suspect that the drug is useless, give up too early. Small quotes: after hair loss desert into an oasis is not a dream!

3、Hair transplant treatment

Rich, capricious, love the beauty, no problem baldness can also be treated with a gorgeous therapy  a wisp of hair. Transplant a tree, uproot it, with a large ball of earth, to ensure that the roots are not damaged, the survival rate is high!

The same is true for hair transplants, which are removed with hair follicles. Transplanted into the disaster area to revive the barren land. Most of the transplanted hair is at the back of the head. Usually after 3-6 months, the new hair will be full of vitality!

What kind of learning methods ca...

Identify your weaknesses, and then make the right choice. There are eight words for good academic performance: strong subjects are strong, weak subjects are not weak. For subjects that you are good at, you can temporarily put them aside, and for some weak subjects, you must make 教育碩士 plans. In fact, although high school has learned more knowledge, the exam is relatively simple and there are really few questions.

1. 獎學金 cross review method

Hugging before the exam is the worst way to learn. Even if you remember it at the time, you will soon forget it. 3. In order to improve the learning effect, the decentralized cross-review method requires continuous decentralized learning. Each subject makes a learning plan according to the mastery level and priority level, and then allocates tasks to each night reasonably.

The key to this method is that the more detailed the learning plan, the better, which knowledge fragments of which subjects are reviewed every day, how long it takes to review each part, and then try to review as planned. This can also avoid "some knowledge" caused by uneven time distribution. "I don't have time to review" embarrassment. While distributing the review, you should also pay attention to interdisciplinary, that is, don't just focus on one subject a day, review math for one hour and change your mind, review Chinese for one hour, and don't review math continuously for two hours to avoid boredom.

2. Review method from difficult to easy

It is estimated that many students have the habit of reviewing in the order of the textbook, starting from the first chapter, and slowly reviewing to the last chapter. The initial comment was very vigorous, and the more tired it became, the more casual it became. However, the design of textbooks is usually from shallow to deep, the first few chapters are simple, the later chapters are more complex and comprehensive, the easier it is to learn loopholes.

2 How to improve grades in high school

Language is to pay attention to accumulation and carefully review questions. I think this is a subject that tests my own literary literacy. As long as my language skills are not too bad, in fact, everyone's scores are similar.

Next is mathematics. Mathematics can't be rushed and learn slowly. Many liberal arts students are afraid of mathematics, but I think the most important thing is to summarize and reflect on mathematics. For topics that we don't know, we should consider what is the essence. We should not blindly ignore the problem. The most important thing is to know the type of the problem and learn how to draw conclusions from the past.

Then comes English. I think English is really not difficult. You should grasp two key points: One is vocabulary and grammar. When you can master it, the improvement of English scores is a natural thing.

However, the immunity boosting effect of fitness exercise is not stored, i.e., the physical and mental health benefits will gradually fade away after a long period without fitness exercise.

The best fitness exercise exercise to boost the body's immunity is a moderate level of stress resistance exercise of 30 minutes to 45 minutes each time, 5 times a week or so, for more than four weeks on a long-term basis.

Some common misconceptions about immunity.

1. winter more very easy to get sick is due to lower immunity no?

Winter because of the colder outdoors, many people are selected to play indoors in a group. Many people gather in a small natural environment to enhance the probability of germs spreading, and therefore more very easy to get sick.

2. often stay up late, irregular work and rest will reduce immunity?

In our long-term poor rest (generally means the total quality of sleep time), will indeed reduce immunity. The autonomic nervous system (everyone's human biological clock) also does jeopardize some cellular immune thematic activities, so we must also enhance the sleep time in case of infection or disease outbreak in our body.

3. Is it true or not that eating mushrooms can boost immunity?

Some people say that eating mushrooms can boost immunity, iPhone can boost immunity, vegetables and fruits can boost immunity ......

This can't be considered wrong, but it can't be said to be completely true. The nutritional content of mushrooms is very good, but the nutritional content of vegetables and fruits, fresh fruits, meat foods, legumes and grains are all very good.

4. What is the use of eating fruits and vegetables alone to boost immunity?

No, you need to eat some of each type of ingredient. Eating fruits and vegetables can consume dietary fiber, vitamins and minerals, but there is no way to consume sufficient protein and high quality oleic acid.

Are all diseases related to the immune system?

Although the immune system is present throughout the body, the body has a lot of system software. There are some conditions that are caused by inflammation or trauma to the body that can harm the immune system, but they are not necessarily the result of a problem with the immune system.

6. Can I take vitamin C supplements to boost my immunity?

The first thing to say is that vitamin C is really good for your immune system, and in the event you suffer from a sensation, your body will also consume vitamin C quickly, so it is feasible to consume a lot of vitamin C.

However, please do not put the key only on vitamin C, because most of the antioxidants (vitamins and minerals) are good for boosting or advancing your immunity. Included here are vitamins A, B, D, E, zinc, iron, etc. Too much or too little of any one small nutrient can harm your body or immune system.

Microfluidic chips, the next rev...

In recent years, microfluidics has developed rapidly with the development of technology. Microfluidics is the science and technology of microscale (tens to hundreds of microns) integrated channel systems. Trace amounts of liquid (typically 10-9 to 10-18 liters) flow under the control of the system by a specific model. The development of such a high-tech microfluidics has actually been heard for decades, and the requirement of microvolume and planarization for biochemical analysis was a good driving force for the development of microfluidics. Since then, the concept of "wafer labs" and microscale integrated analysis systems (μTAS) has been gradually established.

In microfluidic fields, the specific surface area increases as the size of the fluid decreases, showing characteristics different from those of macroscopic fluids. In this paper, three main characteristics of microfluidics are considered: high efficiency of mass heat transfer, relative advantage of viscosity over inertial forces, and significant surface effects. In addition, the highly integrated microfluidic system also promotes the coexistence of multiple fluid phases and multiple interactions. Such properties make it possible to control and manipulate single fluids and fluid interfaces using microdevices, allowing microfluidics to be used in a wide range of applications in physics, chemistry, biology, medicine, and engineering.

Bonding and lamination of microfluidic chips

Today, I would like to discuss with you the revolutionary impact of microfluidics on biochemistry. The application of microfluidics in biochemistry can be very wide, which involves enzyme analysis, DNA analysis (such as polymerase chain reaction and high-throughput sequencing), proteomics analysis, etc. The basic idea of microfluidic biochip is to integrate assay operations, sample processing and sample preparation into a single chip, which gives it high-throughput characteristics. The chip can also play an important role in clinical pathology, especially in the direct diagnosis of diseases. In addition, microfluidic-based devices, such as those that can continuously sample air or water samples, and real-time detection devices can be used to detect biochemical toxins and pathogenic microorganisms. In addition to the above-mentioned assays, microfluidics has become a powerful tool for biologists to study and control the cellular environment, and a "godsend" for new discoveries in cell growth, aging, etc. Next, we will look at some specific examples of how microfluidics performs its role.

In terms of bioanalysis, microfluidics shines in ions, small molecules, and biomolecules such as nucleic acids and proteins, which have led to a revolution in many standard biomolecular techniques. It is a platform for technologies such as multiplex enzyme chain reaction (PCR), reverse transcription PCR (RT-PCR), and enzyme-linked immunosorbent assay (ELISA). In addition, droplet microfluidics, a microfluid, has been able to be successfully analyzed at the cellular level, and many classical cellular manipulations can be done in microdroplets.

Previously, when talking about chemical reactions, the jars and bottles that could not be cleaned by any brush were the ones that came to mind. But today, microfluidic droplets can exist as a small chemical reactor, and researchers can achieve precise control over their environment. It is used in a wide variety of reactions, including titration, precipitation, hydrolysis, etc. A good example is the droplet microfluidic platform for the anticoagulant argatroban. Using this technology, researchers can determine the appropriate dose of argatroban by measuring clotting time with partial thrombospondin kinase activation time on a single wafer. In addition to the aqueous phase reaction, microdroplets also support the organic phase reaction. However, at this time, the materials used to make the instrument must be carefully selected to avoid deformation of the tube due to corrosion by organic solvents. Sulfur hydroxyl polymers are a good choice and have a better organic stability compared to PDMS materials.

A new microfluidic device allows scientific researchers to create alternating electric fields in a three-dimensional natural environment.

Malaysian researchers have designed a three-dimensional microfluidic shaping service platform to test the therapeutic effects of cancer treatment electric fields, a new form of cancer treatment based on the alternating electric fields that have been approved by the FDA for the treatment of malignant gliomas, reports McMasters.

The 3D microfluidic device was developed and designed by an elite team of scientists from the Malaysia-MIT Science Research and Technology Consortium, who created an alternating electric field in a 3D natural environment that is more physiologically appropriate than the standard 3D cell culture media service platform.

This research has shown that electric field therapy reduces the migration and spread of tumour cells. Excitingly, the growth and development rate of tumour cells treated with electric field therapy was reduced by 35% relative to tumour cells that were not treated with electric field therapy. For non-tumour cells, such as endothelial cells around the capillaries surrounding malignant tumours, there was no significant harm.


"With this 3D microfluidic device, physicians will be able to specify the amount of electric field resistance necessary for each patient to be treated, enhancing their treatment outcome."

Most IT businesses have however

The ROI of SD-WANSoftware-defined broad area networking (SD-WAN) is usually a modern merchandise classification. Most IT businesses have however to create their initial buy, though many are undertaking technological investigations and including SD-WAN gateways into their infrastructure designs. On the other hand, the monetary arguments demanded for budgetary acceptance are still a pending action. Although there exists a common belief amid networking team that SD-WAN lessens expenses by shifting targeted visitors from expensive private WAN inbound links to broadband World-wide-web connections, quantifying this as well as other SD-WAN advantages demands a extra arduous strategy.

Software-Defined Wide Area Networking (SD WAN) is a transformational approach to simplify branch office networking and assure optimal application performance.

Quantifying the SD-WAN return on financial commitmentMaking an ROI calculation may be time intensive, so Business Administration Associates (EMA) has generated a paper that gives detailed calculations and explores supplemental quantitative and qualitative added benefits of SD-WAN. Their analysis concluded that, even though the operational and capital charge personal savings are substantial more than a 5-year time period, IT productivity gains and improved community uptime provided even higher payback around the investment. This text explores the broader list of ROI concerns to help you IT administrators create a economical case for SD-WAN investments.

Decreased running expensesAt the core of SD-WAN operation is transforming community connections from personal MpLS backlinks to broadband Web. Secured by encrypted tunnels and built-in firewalls, broadband Online connections commonly price 95-to-99 per cent much less for each megabit-per-second than personal MpLS one-way links. Internet hyperlinks are a great deal of much less expensive that early adopters of SD-WAN significantly increase their bandwidth and they are however conserving network connectivity prices.The economic calculation employed by EMA for any 100-branch community assumes that every branch replaces two 1.5 Mbps MpLS backlinks with a single 1.five Mbps MpLS url and 25 Mbps of broadband Net. This configuration delivers a number of benefits. 1st, an practically 9x boost in bandwidth whilst however reducing in network connectivity prices by 20%. Second, every department can now instantly access cloud products and services without having having to transit a central gateway. Blended, these end in much better overall performance for cloud purposes and high-bandwidth solutions this sort of as video conferencing and prosperous media.Decreased funds expendituresMoney investments make up a smaller share of the network’s 5-year value, but you can find still savings to be had with SD-WAN. Digital appliances, cloud-based administration, and dynamic path choice all add into the savings. Decoupling the hardware in the services, much like digital servers and storage, gets rid of much in the expense and complexity of deploying physical routers.
