Introduction to Baojin Zhai: There are a dazzling array of plaques and couplets hung in Baojin Zhai, such as "Untouchable", "Wonderful Writing", "With Meng Lumen's name and two Xiangyang books passed down through the ages, together Su, Huang and Cai were called the Four Giants" Inscriptions such as "Conquer three people" are the high praise of later generations for Mi Fu's calligraphy and character.
