A rich foreign client had a cat. He spent a lot of money to treat the cat like a king, but the cat refused to lie down.After Dr. Wang's diagnosis, he found that the real problem was the rich man. His circle of friends were all either rich or noble, and he lived a life of luxury and debauchery. He no longer had the ability to be down-to-earth and rely on his own hands to create the meaning of life.Dr. Wang asked Li Yan to catch a lazy stray cat, replace the rich man's original cat, and give the hard-working cat to the place where she was really needed to catch mice.The rich man didn't care that the cat had been replaced. He was very satisfied with the cat that Dr. Wang had selected that was as delicious and lazy as himself, and he happily flew back to China.The rich man paid Dr. Wang a large sum of money as a thank you, and Dr. Wang donated all the money to poor children.
