Once, the son of Li, a widow of Dingjiakeng, was flooded in the whirlpool, and Li hurried to see Dr. Cai. Seeing the child's eyes closed and his stomach bulging like a drum, Dr. Cai sighed and said, "The child is hard to save." Li cried her eyes out about it. Hua tuo went to feel his pulse and whispered to the master, "The child may still be saved!" Dr Cai doesn't believe it. Hua tuo asked someone to lead the cow, first put the child on the cow to control the water, then put the child flat, press the child's abdomen with his legs, raise the child's hands, and slowly land together. After about a quarter of an hour, the child gradually gasped and opened his eyes.
Hua tuo opened another decoction and cured the child. The news that Hua Tuo came back from the dead spread like wildfire. Dr Cai said to Hua Tuo shamefully, "You are better than Linger, and I have no ability to teach you. Go start a business! " Hua Tuo left the teacher's office and didn't start a business, but he traveled around Xu Tu, visiting famous doctors, exploring medical principles and treating people.
