Why did Youku software come down in the browser square dance video? It's Youku software, not square dance.

This is the reason for Youku. Maybe your Youku is not completely installed, so you will download a Youku software when you download something. I usually use my browser to download videos. Just directly search for the square dance video you want on the mobile qq browser Baidu search, and download it to your mobile phone anytime and anywhere to watch.
