Specific practices:
1. Cut the beef into pieces and soak it in tap water for 3-4 hours, during which the water can be changed several times.
2. Boil a pot of boiling water, add a little yellow wine (white wine is also acceptable), pour in beef until the water boils, turn off the fire, remove the beef, rinse it with tap water (rinsing is also acceptable), and wash off the blood residue on the meat.
3. Add water to the beef pot, add onion and mashed ginger, and turn to low heat for stewing.
4, stew until the beef is rotten, remove the onion, add salt, add tomatoes (you can put tomatoes early if you like heavy taste), and more tomatoes can make the soup red and bright.
5, stew until the tomatoes are slightly rotten, the soup color is red, you can add potatoes and lotus root white, stew until the potatoes are cooked, add chicken essence and a little pepper.
