Why did Zhu choose to create Reading Random Thoughts here?

Creative background: In the second year of Qingyuan (1 196), in order to avoid the disaster in Han Dynasty, Zhu and his disciples, Cai Shen and Huang Zhong came to Wuyitang near Shuanglin Temple in Fushan, a new city (now Zhushan Village, lichuan county Township) to give lectures and wrote a poem "Fushan". During this period, he traveled between Cheng Nan and Nanfeng. Now, at the invitation of Li Yuanji and Deng, he wrote an Inscription of Sergeant Jianchang, which greatly praised Jianchang talents. At the invitation of Wu Lun and Wu Chang brothers in Hamawo Village, Shangtang, Nancheng County, he gave lectures in the village, wrote Rongmu Xuan for Wu's guild hall, Book House for reading pavilion and Shecang Ji for the Shecang founded by Wu brothers. In the village, he also wrote a famous poem "Ask the canal so clear that there is flowing water at the source" ("Reading"). After Zhu left the village, the villagers changed Toawo village to Yuantou village. In the Republic of China, a living water town (now Shangtang Town) was built in memory of Zhu. The rock wall of Nanfeng Ceng Gong is engraved with the word "Yan Shu" inscribed by Zhu, and the wall of the small pool under the cave is engraved with the word "Mo Chi" inscribed by Zhu.
