Huitu Com is very popular, that is, there are always many people watching it when it is uploaded, but no one buys it. The same manuscript has been hanging on the wisdom road. Com and fertile soil. I want to sell a lot of things online, although my clicks on Tutu are much less.
"Red China" was not uploaded, but only observed, with few clicks and downloads. People outside the design circle probably don't use this network very much, and there are many designers inside.
On behalf of my short-term opinion, I have just been a seller for a long time.
