Baidu's first social network product "t.baidu.com" quietly launched to invite the whole network to test. Different from the existing SNS platforms in China, Baidu has adopted a "real-name system" for registered users, and the user account needs to be bound with the mobile phone number, which aims to create a more authentic and honest social platform. In a nutshell, Baidu now has a real-name authentication micro-blog called "Say".
