In Putuo, Lu Mingtong explained: "There are some things that people will only tell strangers but not the people around them." At that time Zhou Sizhe thought, "I don't want to be a stranger to you!"
When they met again in Shanghai, Lu Mingtong thanked him, "Stranger, thank you for giving me courage." Zhou Sizhe: "I can give you courage, and I can give you everything else you need!"
In Beijing, Zhou Sizhe said, "I need you."
