       The first reason is that I'm recovering the now-closed [Tietiequan](https://tangled.org/@dwn.dwnfonts.cc/bluesky-circle) app and found that some API has changed so I have to rewrite it via vanilla JS.

       The second reason is that I'm a newbie in ATProto, wanting to know how ATProto is, and how this can be represented in Python.
