In Lust, Caution directed by Ang Lee, at the critical moment of assassination, Tang Wei finally couldn't help but tell him weakly about Tony Leung Chiu Wai's delicate and tangled feelings: Let's go. Tony Leung Chiu Wai reacted, and Liu Xiang ran away, leaving people waiting for the assassination mission standing there. Before he could act, he failed and dispersed, so Tang Wei walked out of the door and didn't see the murderer in the street. But Tang Wei knew that when she said "Let's go", she and her companions could not escape. They sat aimlessly on rickshaws and looked numbly at the people in the street. She wanted to commit suicide by taking poison, but thinking of her classmates in her mind, she gave up suicide and chose to accept the same fate as them.
