1. Wash the beef tenderloin, slice it, drain and set aside, add 5ml of light soy sauce, a little sugar, a teaspoon of oil starch and mix well for sizing (Secret: the secret to tender beef slices, add light soy sauce or water several times to make the beef slices) The taste will be tender and smooth if you eat it thoroughly. Using light soy sauce instead of water can make the beef slices more delicious)
2. Put a small amount of oil in the oil pan, add a little pepper and chili until fragrant, add the chili sauce and stir-fry evenly
3. Wash the bean sprouts and stir-fry in the pot
4. Add 15ml light soy sauce, add a large bowl of boiling water, cook for a while, add the vermicelli, cook for a few minutes, and wait (I like to cook longer, bean sprouts and vermicelli are more delicious)
5. Bean sprouts and vermicelli are delicious, remove and place in a bowl
6. Bring the soup to a boil over high heat, put the beef slices in the pot, slice, cook and change the color, remove and place in a bowl, sprinkle with garlic and chopped green onion
7. Wash the pot, dry it, add a small amount of oil to heat, then pour it over the chopped garlic and chopped green onion until fragrant
