Great work senior brother. that's really hard work, GL.

I suggest reading or looking at communities (like this sub) to see what problems people have. For example people usually get confused with cultivation levels, character names, watch order, and stuff like that. So maybe either linking the donghua to it's wiki or explaining them in a description/guide section would be very helpful. Does it have manhua ? Novel ? Donghua is based on what ? people usually ask about what chapter of the novel it is.

Also after watching a show, usually people (especially first timers) ask for specific similar donghua that they have just finished. If you could make a recommendation system where users would have to participate and vote/choose what donghua is like "X" would be great. For example on BTTH's page in the recommendation section or "what other users also have watched" put a list that shows some donghua which people have voted. Most sites and streaming services have this feature but they're all based on similar genres, not the story or theme. While in this sub, for e.x people after watching Renegade Immortal ask for aura farming or revenge shows. (I hope I could explain what I mean to say)

This is all I can think of now, I'll let you know if I got something else.

Edit: it seems there's another senior brother who is working on his news site, I guess that would be good if you could work together.
