What is the SMS incident of bigbang Dacheng?

The first thing is the birth of a family. There is a game in the 23rd issue, in which you tell a secret of a family member that only you know, and let this person guess what you wrote. Dacheng's answer is that someone at home saw texting with members of jane doe idol groups, which was the beginning of the SMS incident. Dacheng said that the other party sent a text message to say hello, and Dacheng also politely replied hello, and then the other party replied "I hope you today." Then Dacheng politely replied' thank you'. Because the other party knew that he was shooting an advertisement that day, it was still more influential among bigbang fans. Many people guess who it is, and the family often mentions it to stir up Dacheng. Later, people knew it was a "scandal" of Carla's youngest son, Jiang Zhiying. In the first season of The Birth of a Family, it was specifically said that they were idols, so everyone paid too much attention. In fact, the two of them are nothing. Dacheng also said that after this incident, the other party has nothing to do.
