Ni Ping apologized to Song Dandan on the show, and they made up 20 years later. What happened that year?

? Ni Ping apologized to Song Dandan on the show, and they made up 20 years later. What happened that year was also because of a joke, so we haven't contacted each other since. It is understood that at that time, because they were also a gathering between friends, Song Dandan also introduced Ni Ping to his friends as his best friend, but then Ni Ping jokingly said, Do I know you? So this sentence really hurt Song Dandan's feelings, so after that, the two people stopped contacting each other, until this program made it clear that they also untied the knot between the two people at that time and became good friends again.

However, through this incident, I also hope that everyone can understand that many times, you must pay attention to the discretion of joking with yourself and the occasion where you are joking at this time. These aspects also need you to pay more attention to yourself, because you really didn't mean to say this yourself, but giving others the feeling that you don't pay attention to this matter and this feeling between you naturally leads to this misunderstanding between two people, so everyone is the same. ?

There are misunderstandings between myself and my friends, so be sure to explain them clearly. Don't just explain to anyone. That's too bad.

So to sum up, Ni Ping apologized to Song Dandan on the show, and they made up after 20 years. What happened that year was also because of a joke.
