Gao Shi and Guo Ziyi were good friends and served as officials in the government at the same time.
According to an article published by Changlefang who inquired about Muotao, in the movie "Chang'an 30,000 Miles", Li Bai left behind to guard and Gao Shi traveled a long distance to beg his brother Shu Han to pardon Guo Ziyi. This is a fabricated story. In real history, only Li Bai was the one who rescued Guo Ziyi, so there is no historical evidence that Gao Shi saved Guo Ziyi.
