Is the subtitle protected by the copywritght? In that case, I do not think it is easy to download to your desktop freely.

Whereas you can download the whole film from youtube to your desktop though.
I do some subtitle work on youtube and if any question about Chinese subtitle, please inform me and wish I can help you.

I think there should be no this complete chinese TV dramas‘s subtitles separately, a least I had never seen this things before,and I also try to check the web but I can't find it. In fact that ‘s a really good way to learn languages by the local dramas so I do it too. Fortunately, there are many chinese subtitle-teams, they translate the other country‘s dramas or movies into chinese and they also make the bilingual subtitles sometimes.That‘s really helpful to me,but I also need to type this subtitles in WORD by myself because they usually don't put it on internet separately. So...

And If you need some part of the TV dramas that you really want to learn, maybe I can help you to make it, but it's gonna take some time.

@Jack, thanks for the offer. I am looking for the complete subtitles. Though I will come to you for specific questions if necessary.

@sampdoria, thanks. Do you have a link?
