Who attended Wang Xizhi's Lanting meeting?

It is said that on March 3rd, the 9th year of Yonghe (353), Wang Xizhi and 4 1 person, including Wenyou, Xie An and Sun Chuo. It is a custom to hold a ceremony in Lanting to meet the water and eliminate disasters. Drinking and writing poems, Wang Xizhi's "Writing a Pen with Cocoon Paper" is a drunken preface, with 28 lines and 324 words. After waking up, I wrote hundreds of stories, which were not as good as the original, but were called "the most proud book". Wang Xizhi regards Preface to Lanting as a family heirloom, which has been handed down from generation to generation and has been handed down to Sun Zhiyong, the seventh generation of the Wang family. However, Zhiyong became a monk for some reason, and naturally there were no children behind him, so he passed the original ancestral book to disciple Cai Bian. In the early Tang Dynasty, Li Shimin collected a large number of Wang Xizhi's calligraphy treasures and studied them frequently. He praised the original "Preface to the Lanting Pavilion" and paid a lot of money for many times, but nothing came of it. Later, it was found that the original preface to Lanting Collection was in the hands of a monk named Cai Bian in Huiji, which led to the story that Emperor Taizong defrauded the original preface to Lanting Collection and was buried in Zhaoling with Emperor Taizong. This story adds a legendary and mysterious atmosphere to the Preface to Lanting.
