This is a great project. I have some suggestions about the three-level address of the layarea. I have probably looked at the data structure of the address. It is not easy to maintain this kind of data in the later stage. Generally, the data needs to interact with the database, otherwise it becomes a decoration
很棒的项目，关于layarea地址的三级有点建议，我大概看了下地址的数据结构，这种后期不大好维护，这些数据一般要和数据库有交互，不然成摆设了
