Kao Ni La Zhanshen Xitong

we love a self-aware anime / donghua
in this list are some shows that break the fourth wall and reference other anime
(these are only ones that i have watched im sure there are others)

Main character is either OP from the get go or becomes OP as the series progresses (Will mention if it's the latter)

1. No animes where MC is OP but we don't get enough action (EX: I've been killing slimes for 300 years and Problem Children Are Coming from Another World, Aren't They?)

Collection of all 2D Fantasy & Supernatural Donghua (only the first season entry)

Speaks for itself, but it can contain chinese folklore or chinese historical elements, like spirits and dynasties

Anime where the main character has a stat and/or skill system where they get stronger with increased stats and skills. There is a mix of series where the main character has a special attribute window that only they have and ones where the world uses attribute windows as part of the theme of anime.

Anime where the main character is an otaku or Japan/gaming fanatic.

Otaku Definition: Japanese term (sometimes pejorative) for fans that pass a large part of their time and resources in a hobby they are passionate about and that directs their life at home, such as animes, mangas, video games and elements of modern Japanese culture.

Anime where the main character is a shut-in or NEET with little to no social life. This includes series where the main character doesn't explicitly state they are a shut-in but instead protrudes behaviors of such characters.

Anime where the main theme is gaming - playing, developing, learning etc.

Anime where the main character transmigrates into a new world. Transmigrates could be through reincarnation, time skip, traveling between worlds etc. I can guarantee you haven't seen at least one isekai anime in this list, and if you and I need to be banned from the isekai theme.

2D Chinese anime/donghua that I recommend personally with passable animation and art styles.
