I want to install a potato net software square dance. What are the specific steps? Ask a good friend of mine, thank you. I don't know how to install software.

Select tudou.com's square dance video, and click Play. When 10~20 seconds after the advertisement, find a downward arrow with a short horizontal line icon at the bottom of the screen, the word "download" will appear, and the prompt window of "download potato video with potato download tool iTudou" will pop up. Then install iTudou according to the prompts, and you can download TV dramas and movies such as square dance in tudou.com after installation. Having said so much, the landlord didn't even get a reward. Lack of motivation.
