Mr. Liu was widowed in his later years and had an only son. Mr. Liu regarded his son as a treasure since he was a child, and his son was married. My son and daughter-in-law live in the East Room, and Mr. Liu lives alone in Westinghouse.

One day, Mr. Liu heard the sound of a chopping board in the East Room, and thought, this is jiaozi's daughter-in-law chopping stuffing. Mr Liu likes to eat jiaozi. He thought that his son and daughter-in-law would come and invite him to eat jiaozi with them. He hurried out to get garlic and peel it. Mr. Liu was waiting for his son in Westinghouse, and his daughter-in-law came to call him. But I waited for a long time and didn't invite him to eat jiaozi. "I said to myself," Maybe I want to eat jiaozi too much. Wait a minute! " After half a ring, Mr. Liu heard the sound of shabu-shabu ...

? It turns out that my son and daughter-in-law have all finished eating. Mr. Liu is angry and annoyed, and he is not in the mood to cook by himself. Later, when this incident came out, people made up the slang with sympathy, "Teacher Liu peeled garlic twice." To express their hatred for failing to honor the elderly.
