How to send Baidu invitation code?

After you accept someone's invitation and activate Baidu Hi, log in Baidu Hi about 10 minutes later. Add your friend's Baidu account or his email address through the Add button below. Baidu's system will naturally send him an invitation letter from Baidu Hi.

Moreover, if you are a Baidu account, if you have friends on your account, you will add them to your Baidu hi friends by default when you log in, and naturally send invitations to each of them, if he is not a Baidu Hi user.
