So this is a tip of advice for vertical chinese dramas only since that's my main interest here but I have my own YouTube drama page where I sort by catgeories and actor names. cdramawho - YouTube
Also, many of those pages whose videos are in my playlists are worth a follow and there are other YouTube channels dedicated to playlists like mine, such as THEBLACKCATSPLAYLIST - YouTube and TheBlackCatsTV (same person, different channel)
For our vertical short cdramas, any page listed for them you go to here on MDL, JWells will have the links posted in the comments.
Now, for other dramas that are longer you can usually use certain streaming services like YouKou or Viki app. There's also IQIYI. I hope this little bit of info helps but all these streaming services I mentioned are usually paid services.
