You are cooking corn sparerib soup. Put the meat in a pot, add water to boil, roll, boil the bleeding bubbles, and pour out the water. Put water in the casserole, ribs in the pot, ginger and onion in the pot together, drop a little white wine, light it, boil the casserole water, turn to low heat and cook for about 30 minutes, then add corn and stew together for 10- 15 minutes. After cooking, remove the ginger slices and onion knots and add some salt to taste. The time is about 2 hours. In fact, it takes about 40 minutes-1 hour to cook, and the rest of the time is to cook soup. Of course, the longer the better.
