Since I've been adding manhua series to the site, I can't find first release dates for any manhua on AC.QQ. Do you know other sites I can check other than baidu?

This is just with my limited googling/google translate skills, but I ran into one website called bugumanhua that seems to at least have some kind of date posted, and if the series is on billibilli, it references that as it's source. Although I suspect this date includes trailer/teasers/previews that may be posted before the official release of chapter 1, since I used Devil's Luck as an example test, which the website stated the date for that was 2021-10-28 but chapter 1 was technically announced for January 15th, so I'm assuming the teaser/series announcement for it was back in 2021.

Hopefully someone might know a more accurate one (or at least a website that can show the date each chapter was posted)

Thanks 😢 I know I encountered some random non-official site where it did have the start date, but I don't remember the name and it was only that one site... will see if the site you mentioned has the right date, cause otherwise I can only resort to finding the date of the earliest comment for each manhua on the AC.QQ page...
