Today, I received a friend's invitation code from Baidu, and almost everyone is talking about it on Weibo. ldquo; Baidu say rdquo; (t.baidu.com), I went to have a look. Because of the invitation code, it's easy to arouse people's curiosity. When registering, I was asked to enter my mobile phone number, which must be authenticated by SMS. Secondly, it is required to enter the ID number, which will automatically verify whether the real name and ID card are unified after entering the ID number.
