Introduction to Dongshan Thatched Cottage: Guanzhi Mountain has left many cliff stone carvings in the past. The most precious ones are Lin Zexu’s climb to Guanzhi Mountain, the handwritten horizontal plaque "Jiangzuo Fengliu" stored in Dongshan Thatched Cottage, and the "Sikuquanshu" written by Qianlong of the Qing Dynasty. Chief editor Ji Xiaolan inscribed "Chasing the East Mountain" when he was the governor of Fujian College.
