Tianya, Douban, Maopu, which forum is older? What's the difference between them?

Douban was ruled out first ~ now after 90, it is an army. Look at all the posts. Are young people who want to learn some literature. Of course, they will go to Douban to find some film reviews. There are many people who write well.

Cats are basically concentrated in the post-80 s generation, and there are often some posts in which 80 s and 90 s scold each other. The basic age is 20 or 30, and I feel that the content quality is declining now.

Tianya's age is very broad, and this website itself involves many topics such as current affairs, politics, literature, etc., unlike the other two websites that lack these sections in their settings, and many deep eight diagrams come from Tianya, so unofficial history still goes to Tianya ~
