Mainly because of the short stories of dialects.

This is a joke that the local people told me when I was doing social education in Guangfeng, Jiangxi Province more than forty years ago.

Guangfeng dialect is inherently difficult to understand. We can still understand the people who studied there, but we can't understand a word of the rural grandmother's speech.

It is said that a foreign son-in-law visited Guangfeng's mother-in-law's house. The mother-in-law was very happy to see her son-in-law coming and prepared a lot of dishes. Mother-in-law cooked a dish and let her son-in-law take it away. The son-in-law asked, "Where to take it?" "Take it to bed!" Mother-in-law also pointed to her son-in-law. As soon as he saw a bed, he brought the food to the bed. The mother-in-law fried two more dishes and said to her son-in-law, "Go and have a look, be careful of flies!" " ""Never mind, I wrote down the bill! "Mother-in-law listened to the puzzling, just look at it in the past. As soon as she saw it, her son-in-law took all the dishes to bed. Really in distress situation!

Originally, Guangfeng dialect called this table' bed' (homophonic.

PS copied it.
