First of all, China's dishes are usually named after famous local people or according to their dietary preferences. For example, Dongpo pork, a famous flavor dish in Hangzhou, was named to commemorate Su Dongpo's previous contribution in Hangzhou. The name of this dish is to praise his merits and let future generations remember him.
Secondly, China dishes are named according to their characteristics and producers. Nowadays, old lady cakes are popular, which means that a man goes out to do business and comes back to bring snacks to his wife. But his wife did say it was terrible, not much better than her cooking. Later, his wife transformed the snacks and made new cookies, which were really delicious. This kind of biscuit was made by his wife, so he called it the old lady's cake.
There are also dishes named after regions. For example, Sichuan cuisine, which we prefer to eat, is a very spicy dish that Chengdu and Chongqing eat more.
In fact, there are many ways to choose the names of dishes in China. The name of the dish is just to highlight the characteristics of the dish, or some people want to be unique, so you don't have to worry about the origin of the name of the dish, just be delicious.
