Interpretation and analysis: Because rural people often work in the fields, the day's work is very hard, and the conditions in rural areas are not as superior as those in cities, so farmers don't have high requirements for life, so they can eat and drink enough.
It is very beautiful to have a meal in jiaozi once in a while, and it is also the most comfortable time to rest on the kang after work, so there is a two-part allegorical saying that "it's delicious but not as good as jiaozi, but it's better to be comfortable backwards".
Extended data:
In the past years, life in rural areas was very poor. Food like jiaozi could only be eaten during the Spring Festival or on big occasions. At that time, it was considered very extravagant to eat jiaozi. At ordinary times, farmers' lives were all sweet potatoes and cornmeal cakes.
It is rare to eat a meal of white flour in jiaozi, which is delicious on earth. People who eat rice and white flour every day are tired of it now, and corn coarse grains have become good things. Therefore, this proverb is also to express people's highest praise for this kind of food in jiaozi, that is, there is no more delicious food than jiaozi, which is the origin of "delicious but jiaozi".
