New to Cdramas - Questions around budgets, releases, etc

Hi everyone!

I'm fairly new to C-dramas and have only watched a few so far. Right now, I’m making my way through Joy of Life and, as someone who enjoys data, I’ve been curious about certain aspects of the industry.

I’ve come across mentions of Yunhe and the ranking of dramas based on production budgets (S, S+, etc.). Is there a reliable source where I can track this information for both past and upcoming dramas?

Additionally, I’d love to know the best place to find historical viewership data—something that gives a quick overview of which dramas were the most popular in previous years. For example, I saw a post mentioning that Joy of Life 2 was the most-watched drama last year. Where can I find similar insights?

Lastly, is there a comprehensive site for upcoming drama releases? I’m coming from the anime and K-drama space, where platforms like MyAnimeList and AniList provide detailed production, staff, viewership, and scheduling information. I’ve explored MyDramaList, but it seems lacking compared to those sites. Are there better alternatives?

Would really appreciate any information, I know this may be an odd request. Or maybe it isn't, I'm not too sure as I'm quite new to Cdrama. Anways, its been a blast so far.
