Introduction to the white marble screen wall: The white marble screen wall that you first see after entering the gate of the park is carved from white marble from Sichuan. The front wall is engraved with a famous saying by Xu Shen that summarizes Chinese characters: "The one who covers the characters is the master of art. This is the beginning of the king's government, so the predecessors looked down upon the latter, and the descendants learned about the past." It was inscribed by Mr. Zhang Zhihe, a famous contemporary regular script writer. On the back wall are engraved 540 radicals of "Shuowen Jiezi", written by the monk calligrapher Mengying of the Song Dynasty, and the inscription was inscribed by his disciple Guo Zhongshu, a philologist of the Song Dynasty.
