You can download videos and songs from Youku.com
I’m no tech wizard, and I just followed the guides below on how to do it:
https://www.techwalla.com/articles/how-to-download-movies-from-youku
http://youku-downloader-xmlbar.soft112.com/download.html

XMLbar works well with other chinese streaming sites such as tudou, iqiyi, 56, qq, bilibili.
I have found http://v.qq.com/movie/ to work particularly well with XMLbar video download program.
Downloading from chinese streaming sites has the added benefit of embedded Chinese subtitles.
Note: If the video on the site has a ‘VIP’ sign, it likely means you likely won’t be able to download it via the XMLbar.
Most of the newish movies are VIP, but classics like Neverending Story, Labyrinth, Free Willy etc are downloadable.
I have found a good way to search for streaming movies is via Bing search engine as runs locally so searches the Chinese sites. Type in the movie you’re looking for and select the ‘video’ tab, and see which streaming site has the movie you want.

For newer movies, you can torrent them. I like YIFY torrents as you can easily find the corresponding YIFY subtitles. http://www.yify-torrent.org/ + https://www.yifysubtitles.com/
I use http://download.cnet.com/VSDC-Free-Video-Editor/3000-13631_4-75764187.html
to add (embed) Chinese subtitles onto English Movies.

If you don’t want to embed movies you can always use Splayer.
Just make sure the Video File and the subtitle file are in the same folder.
You can even play two alternate subtitles at the same time.
