For my previous posts, most of them are really basic tutorials and short essays about one aspect. So I feel like I have to improve the post quality. I will keep those short posts as personal notes and when I get something more meaningful or want to write on some aspects in greater details, I will make a post.

One more thing is that, there will be posts in chinese later simply because most of my readers might be chinese. BTW, it’s easier for me to write in chinese. But I will still write English posts and youtube videos if I can. Good luck.
