In the meantime, Lin is busy cleaning up the house. When Lin asks if he needs help, he is told that his brother, Cai Ling, is as good as Lin's brother, and that Lin should be quiet and let Cai Ling do the work. Lin is so tired that he falls asleep on the floor. He wakes up the next morning to find that he has been living on the mountain for a month. He wants to go back to the town and buy some things. He tells himself that he wants to save people as doctors, not as people who take lives for a living.
