This kind of herbs are also recorded in the letters, such as water chestnut paste, walnut paste, herb paste, bird paste (above "Seventeen Paste"), chamaejasme chamaejasme paste, and water chestnut, walnut, plum, orange, apple, chrysanthemum and chamaejasme chamaejasme mentioned in Huang Gan paste. Wang Xizhi wants to find herbs in the mountains and grow herbs in his garden. Twenty-nine biographies of Seventeen Posts are almost "Sichuan Books", and herbs were sent by Zhou Fu who lived in Bashu. In order to gain vitality and nourish the body, Wang Xizhi focused on health preservation in his later years. Wang Xizhi collected 465 strokes of calligraphy in Fa Shu, and only one person mentioned calligraphy: "Shu is interested, and now it is a cursive script", which is proof.
