Things are cheap in Vietnam. There are also 鈥詪 lot of good food. It's best to sell snacks. And it can be properly improved. Compared with the main meal, Vietnamese snacks are much more famous. The most famous one is the "Vietnamese small roll noodle". In Kunming, Vietnamese small rolls have always been very popular and have penetrated into people's lives, becoming one of the snacks comparable to rice noodles, rice vermicelli, noodles and so on. Other than that, Vietnam's comparable snacks include chicken noodle, snail noodle, river noodle, spring rolls and so on. The "Vietnamese small roll noodle" that has been introduced to China has been quite different from the authentic Vietnamese small roll noodle, which has been improved for the Chinese people's taste, and is therefore welcomed by the Chinese people. In contrast, the taste of Vietnamese noodle rolls is a little less favorable. Unlike the Chinese, authentic Vietnamese rolls are usually not stuffed. The few that do are not stuffed with meat, but only with pickled vegetables like winter vegetables and peanut sesame seeds to adjust the flavor. However, the biggest difference lies in the preparation of the dipping sauce. In China, people usually use soy sauce as the main ingredient to make dipping sauce, while Vietnamese people usually use fish sauce as the main ingredient, diluted with coriander, crushed chili peppers and other seasonings, the flavor is much lighter. The most special thing is that they like to add some western-style ham cubes inside the dipping water, which seems to be to increase the nutrition, and it is also a kind of compensation for the lack of meat filling in the small rolls of vermicelli. Many snack bars make their own small rolls and sell them freshly made, which is a slightly more primitive way of ensuring freshness than uniformly purchasing the food. This also allowed me to learn about the process of making the rolls, which was a great way to get a better understanding of the food while having a good meal. Hanoi's most famous snacks are all kinds of rice vermicelli, with chicken vermicelli and snail vermicelli being the most popular. However, after we came to the narrow old street with the guide and tasted the authentic Hanoi rice noodles, all of us exclaimed that we were fooled. In my opinion, the biggest reason why Hanoi's rice vermicelli is rated as "unpalatable" by Chinese tourists is because of the huge difference in flavor. Originally, the flavor of the soup is very light, and you can even taste the sourness of the rice noodle itself. The chicken pieces or snails added to the soup have no flavor, and are basically boiled in light water and then put in. Those snails don't have any attraction other than adding a fishy flavor to a bowl of rice noodles. To Chinese people with heavy tastes, of course, this kind of thing would be incredibly unpalatable. Although in general, Vietnamese food is relatively unappealing to national tastes. However, in Vietnam, there are two things that are considered delicious and left a deep impression on me. One was the Vietnamese hamburger. This is the name I gave to a breakfast often eaten by Vietnamese people (especially in the south-central part). Because they don't have a specific name for it, they just call it "bread" in general. The word "bread" does not reflect the characteristics of this food. The main part of the Vietnamese hamburger is the French bread brought to Vietnam by the French, which is usually pike-shaped, with a hard, crunchy crust and a soft interior. The bread used to make Vietnamese hamburgers is usually 20 to 30 centimeters long. To eat, you cut a slit in the middle of the bun lengthwise, put in eggs, meat sauce, meat floss or slices of meat (there are many to choose from), cucumbers, tomatoes, bok choy and other vegetables cut into small slices, and then add a variety of seasonings (many of which I don't recognize), or about ten things, and then close the slit, and you've got a Vietnamese hamburger. Compared to the western hamburger, the Vietnamese hamburger is much more complex, the taste is more in line with the habits of the Oriental people, the content of vegetables is more, the degree of grease is much weaker, as a daily breakfast, more nutritious and healthy than the western hamburger. Another thing is Vietnamese coffee. Under the influence of the French, Vietnamese people have developed the habit of drinking coffee. Coffee in Vietnam is a popular drink for all people just like tea in China. Cafes are found in cities and towns, as common as teahouses in ancient China. Even in small, remote and backward towns, you can easily find cafes. Cafes are an important place for Vietnamese people to socialize. Most of them are poorly decorated with simple layouts and look no different from snack bars. Accordingly, the price of coffee in Vietnam is extremely low, so cheap that it is hard for Chinese people to imagine. A cup of distilled coffee made from coffee beans on site in a cafe can cost as little as three to five yuan. This low price is not only in the absolute sense, but also in the relative sense. I roughly calculated that the price of dishes in Vietnamese restaurants is about 1/2 to 1/3 of the price of similar dishes in China, but the price of coffee in Vietnam is only 1/10 to 1/20 of the price of similar coffee in China, so you can see the huge difference. Low price does not mean low quality. We drank coffee in small cafes in five or six cities in Vietnam, each of which is made on-site, and the taste is definitely not inferior to that of a cup of coffee in domestic cafes, which often costs tens of dollars. If we take the common "Shangdao Coffee" in China as a reference, then about 80% of the small cafes in Vietnam make better coffee than Shangdao. During the time in Vietnam, although there is no good food, but every day you can drink good coffee, and drink frankly, drink comfort, but also a kind of compensation.
