Comments on the predecessor

However, many people still break up and like to write notes to their predecessors 10086, 100 10, 10000. These figures must be familiar to everyone. They are the official customer service numbers of China Mobile, China Unicom and China Telecom. Everyone receives a lot of reminder messages at these numbers every day, and everyone doesn't care much. Therefore, this number is set so that you don't care about your predecessor and treat the other person as an irrelevant stranger.
