Baidu knows that there are homework help, Baby Know, Thumb Doctor, Baidu Ask Coffee, Baidu Experience, Know Daily and other sub-products and related websites.
Similar Q&A platforms are: 360 Q&A, sogou Q&A (original Soso Q&A), Zhihu, Sina Q&A, Tianya Q&A, and divided answer (paid).
In addition, Taobao, Yixin, 58 Tongcheng and other websites or software have built-in corresponding Q&A sections, and Weibo, Post Bar and Forum also have similar Q&A functions.
However, it is mainly Baidu that can redeem points for gifts. 360 Q&A users are relatively few, and there are fewer questions, so it is naturally more difficult to earn points. Integral mall, a questioner in sogou, never put the gifts on the shelves, let alone ask questions on Sina.
