Sun Miaoxi, a young actor, was born in the military, but this time he played Gu Jinfeng, a lively and infatuated "non-mainstream woman in urban fashion" in the TV series "First Marriage", which was very different from his own personality in reality.

In the play, Gu Jinfeng tried her best to catch up with Chen Zengqiang and made many jokes. With her excellent acting skills, Sun Miaoxi made this role lively and joyful, which was very pleasing, but the most impressive thing was her two crying scenes in the play, which made people feel deeply grieved. In private, Sun Miaoxi is very strict with himself, and he is never late for filming. Her play and personality have been well received by the director and the crew.
