Today I went to see a movie. I was so happy. Today we saw 30000 li in Chang'an. The main characters were Gao Shi and Li Bai. What impressed me most was that Li Bai was demoted at the beginning of Baidicheng. This poem was written when Li Bai was released. Another one was that Gao Shi died two years after Li Bai died. Today I saw 30000 li in Chang'an, and the next day I saw 30000 li in Chang'an, I have gained a lot of knowledge about history, which poem was written by Li Bai.good-bye
