On the boulder in the northwest of the town. According to the introduction of the game "Bao Mengke Zhuzi", we can know that Zhuzi's sonic boxing school is on the boulder in the northwest of Xuezha Town. "Blood" is a first-class Chinese character, which was first seen in Oracle Bone Inscriptions. Its original meaning is to enlighten children and make them realize, that is, the so-called "enlightenment" in Shuo Wen Jie Zi, which is originally used to express education, thus extending the meaning of mutual discussion, imitation, annotation, narration and knowledge.
