Most folk graves are round, which is also influenced by feudal culture, but I don't know why people thought of this prototype at first, maybe there are some special reasons. Moreover, in the vast land of China, the cultural customs in each place are different, and the interpretation of a cultural custom in each place is also different.
In the long history of China, many feudal customs survived. In fact, sometimes we can't say that they are not good or that they are good. They are just a habit in their hearts, a symbol, representing our adherence to the past culture. And his success has spread to the present, which shows that he can be recognized by most people, which is a very good thing in itself.
Especially in some important matters, such as funerals, weddings, and how to go through each process, there are actually strict rules, and most of them stick to the rules. However, with the development of the times, we modern people have moved to cities, and there are many things that we can't do in cities, which will lead to the loss of some cultural customs. In fact, this is an adaptation to an era.
When an era develops, it will inevitably change. An era has changed, and we will change with it. Only in this way can we adapt to the times. If everyone sticks to the rules and lives in the past, it will be difficult to adapt to this era and can only be eliminated by the times.
