Zhu Lan is located in the southwest of Keqiao District. According to legend, Gou Jian, the King of Yue, was here. Opposite the calligraphy is Lanting, at the foot of the mountain. According to historical records, Wang Xizhi once hosted a banquet here with celebrities on the third day of March in Yonghe, the ninth year of the Eastern Jin Dynasty, and won 37 poems. On a whim, the Right Army wrote Preface to Lanting Collection. After Wang Xizhi was honored as a calligraphy double, Lanting became a holy place for calligraphy.
Lanting National Forest Park, which is adjacent to it, is a unique green world with high mountains, overlapping peaks, surrounded by mountains and streams splashing pearls. Recently, the park has formed a tourist and leisure resort that integrates forest landscape, natural landscape and humanistic landscape of calligraphy holy land.
