Who wrote the most beautiful poem?

It's hard to judge! Whose is the best! There are different representatives in different times, and their styles are determined by their environment. The poems of Xi Murong, Shu Ting, Haizi and Ai Qing are all beautiful, depending on personal judgment and hobbies. If it is instructive, look at the great patriotic poet Lu You or the more realistic Du Fu. Like the beautiful, look at Li Shangyin's love poems.
