The uniqueness of this film lies in its deep integration of crime and food "crayfish", which makes the film find a golden line between duality and typology. From Wang Qianyuan's usual ridicule to his awakened sleep, we can find his inner feelings about Mabel Yuan, which he ignored or refused to admit. He also took risks everywhere, jumped into a freight company to explore the enemy's situation, and found that he wanted to prove his courage, but he was eager to retire-so his face was red when he cooked lobster, and playing chess in the dark was accepted.
