In this chapter, Dr. Manette explains to the audience why she wants to study medicine. She wants to protect her tribe from the abuse of the wealthy Manettes and protect them from the abuses of the rich Manettes. She also explains that she has failed to pass the entrance exam to the university and that the city of Luofu forbids the members of the tribe to enter and leave the city as they want. The marketplace outside the city is where products and goods are traded, and the young people of the Luifu tribe have to live there for their entire lives since they can't cultivate.
