Why can’t I change my name on the popular science certificate in Kuaishou?

Because there is an official time limit.

Currently, Kuaishou can only change your name twice a week. If you change your name more than twice, you cannot change it and you have to wait until next week.

Kuaishou is a national-level short video app. In Kuaishou, you can learn about the real world, meet interesting people, and record your true and interesting self.
