Traditional first aid methods in China

First-aid methods of drowning in ancient rural areas. It is still valid. On the back of the cow, use the back of the cow to control the water in the belly of the drowning person. The cow didn't leave at first, but it was empty. After a while, the cow was allowed to go. As the cattle moved forward, the water in the belly of the drowning man was controlled one by one, and the water was empty, and the drowning man woke up. I've seen you lying face down on the bottom of the pot. After a while, the water will be empty, and it will be fine.
