When it comes to Vietnamese food, it begins to remind people of Vietnamese river powder. Indeed, the Vietnamese river powder, a hundred-year-old Vietnamese food, is integrated into the Chinese and French culture of cooking, with its unique and special taste not only in Viet Nam, but also in the world as Vietnamese migrants. It has been documented that Vietnamese river powder was first brought into Viet Nam by Guangdong immigrants in the early part of the twentieth century and is now the national food of Viet Nam. River powder is a basic food skill in Viet Nam, a recipe for cooks and restaurants, and thus the largest selling point for all Vietnamese restaurants. The essence of the powder is soup. Put the soup on. This river is halfway through. As food growers, while there are no professional chefs, there is no ambiguity about cooking. You see, if you want to be serious, just do it my way. But now it's an extraordinary time, and some of the materials, like the bones of a cow, the oxen, you can make soup with the bones of a pig, the flesh of a pig, or the whole chicken, and that tastes different。
