In this chapter, we learn that daodao has just arrived in Shanghai, and that he has just bought some lunch. He tells his grandma, who is also a member of the Chinese zodiac, that he is planning to serve some delicacies from his hometown. He explains that his blood type is type O, which means that he will be compatible with both men and women of the same blood type. He also explains that the dog and the rat are compatible because they are both born in the year of the animal that corresponds to the year in which they were born. He says that the two animals can rely on one another for the rest of their lives because they both have the same type of blood. He then explains that if a man has a blood type O and a woman has blood type A, they will be in a good position to get married and have a good career. He compares this to a man who has a hair of the male lead and a face of the passerby with no distinguishing features. If the man's hair is plucked off, he will have a face with no features, and if it is removed, it will lead to a severe venous bleeding. He goes on to explain that when two people are happy together, they often want to show off their best selves. However, if they are not happy, they can still be attracted to each other after they have seen each other's true self. If a person is attracted to someone after seeing the true self, then true love is what they are looking for.
