You won't find every single Chinese drama on this platform, but you will find the most popular ones. On this website, certain people are VIPs and some are not. If you want to watch some Chinese drama, you can do so on this site. The main distinction is that VIP users can watch episodes before the general public.
This software is great because the English subtitles are always updated and it is legal to use. When new episodes of the mystery series "The Long Night" by Bai Yu are uploaded to the website, subtitles for those episodes are also uploaded in other languages so that viewers from all over the world can enjoy them.
