Cheng Yu's grandfather passed away, and he left him a legacy. The legacy included a collection of books he had collected for most of his life. It took him a month to sort out the legacy. There was an old dog who always rolled its eyes when seeing him and didn't seem to regard him as its owner. This made Cheng Yu, who had always been trouble-free, headache and distressed, and had to postpone his departure time and again. Oh, there is another one. He left a neighbor for him. The neighbor cut the watermelon and put it in front of him and said, "Cheng Yu, let me help you."
Intention: The man leads the old dog
