Why did Na Ying laugh at Dao Lang?

Hello, Na Ying's joke about Dao Lang is also for the entertainment effect of the program. Actually, they have a good relationship in private. The more they say this, the more popular Dao Lang and Dao Lang are, so many things can't be taken at face value. Things in the entertainment circle are particularly complicated and beyond our understanding. I hope I can help you. It's not easy to answer questions. Please adopt it. Thank you!
