1 means that a person is poor all his life, and his living standard is not allowed to eat more than three dishes at a time.
2, can't eat four dishes, not quantity, but four dishes in life. A dish is a full moon banquet of life, and a dish is your own wedding banquet. Three dishes are your own death banquet, and four dishes are a tribute banquet.
"Four dishes" are used in popular areas
You can't eat four dishes in your life, which is popular in northern China, especially in northeast China such as Heilongjiang, Jilin and Liaoning. Because northerners pay attention to eating, the general standard is four dishes and one soup. Four dishes, one big and one small, two meat dishes and two vegetarian dishes. Saying that you can't eat four dishes is obviously a mockery of poverty.
Taking "I can't eat four dishes in my life" as an ironic discourse reflects the slang elements in proverbs. However, whether it is to hate mud to help the wall or to insult the poor, this proverb is obviously discriminatory and not worth taking.
