I would like to install a Tudou download software to download the square dance, how do I do it? I don't know how to install the software, but I'm not sure if it's a good idea.

Choose a square dance video on Tudou and click on play, after 10~20 seconds of advertisement, when the "main movie" starts, find a down arrow with a short horizontal icon at the bottom of the screen and click on it, then there will be the word "download" appearing and popping up. "Use the potato download tool iTudou download potato video" prompt window, then install iTudou according to the prompts, installed on the potato network can be under the square dance and other TV series and movies and so on. I'm not sure if you're going to be able to get a good deal on this, but I'm sure you're going to be able to get a good deal on this. The first thing you need to do is to get your hands dirty.
