Why did Carina Lau's classmates at TVB say that she was having an affair with her teacher?

Carina Lau graduated from tvbi's No.1 12 artist training class in 1984. According to her own statement in the TVB program "Best Actress", she actually took the exam with others the year before last, just because she failed in Cantonese. At that time, the teacher in charge of enrollment was Fanggang Liu. He is very optimistic about Carina Lau, so he told her to study Cantonese carefully for one year before taking the exam. As long as she passes the Cantonese test, he will definitely accept Carina Lau. Liu didn't pay much attention to the teacher's words because he was an accompanying exam. As a result, a year later, the teacher took the initiative to call and ask her why she didn't sign up. Liu was embarrassed to tell the teacher that she didn't practice at all. As a result, she could no longer take the Cantonese exam, but Fanggang Liu made an exception and accepted her.

In order to learn Cantonese well in Carina Lau, Miss Liu specially found someone to teach her Cantonese and gave her many opportunities to perform. After a long time, it is inevitable that someone will gossip that she is having an affair with the teacher. Carina Lau doesn't care about this, thinking that the Qing dynasty will clear itself, and time will tell everything. In fact, Mr. Liu's students, Carina Lau and Tony Leung Chiu Wai, later invited Mr. Liu, who will immigrate to Canada, to dinner. During the dinner, Mr. Liu said it was a little cold, and Carina Lau put on Tony Leung Chiu Wai's sweater for Mr. Liu. Teacher Liu was very happy and joked: now I also have a champion sweater, and the feelings between teachers and students are beyond words.
