The Orchid Pavilion Gathering of 353 CE, also known as the Lanting Gathering, was a cultural and poetic event during the Six Dynasties era, in China. This event itself has a certain inherent and poetic interest in regard to the development of landscape poetry and the philosophical ideas of Zhuangzi. The gathering at the Orchid Pavilion is also famous for the artistry of the calligraphy of Wang Xizhi, who was both one of the participants as well as the author and calligrapher of the Lantingji Xu (Preface to the Poems Composed at the Orchid Pavilion). Sun Chuo also wrote a preface, which is somewhat less famous.
