First of all, I was upset after reading Lianxuan and seeing it collapse, so I poured it out all at once. If I didn't grasp the hierarchical structure of the article well, please forgive me.
I didn't expect that a small article like this would get a lot of clicks or collections. Anyway, I just felt uncomfortable not telling others about it, so I disconnected from my other articles and started this one.
