So which play did Hugh watch? According to my calculation under this answer, before filming Good Times, Sunny's only influential work was the female number two in I Love My Boyfriend. Therefore, it is likely that Hugh saw the play and thought the role was suitable for Mao Xiaochun in the Prosperous Age, so he recommended Sang Ni to Wang Liping. Then Wang Liping called Sang Ni and said something like "The crew decided to let you play Mao Xiaochun".
Some people say that Sunny once played Guo Jing's mother-in-law Feng Heng in The Legend of the Condor Heroes starring Hugh, and once cooperated with Hugh. This is actually inaccurate. Hugh was the first hero at that time. She didn't play with a quasi-walk-on like Sang Ni. Later, Hugh admitted in an interview: "I didn't see her on the set."
That is to say, while knowing Hugh, she suddenly found herself in love with a man, and it was a man. Of course, the true meaning of this Weibo can only be fully analyzed after the truth is completely revealed. What is certain now is that Sunny and Hugh met in March, and at the same time, she found herself in love with a man.
