Gao Shi was dull and taciturn, and his social circle was not as wide as that of Li Bai. He was a careful person and admired Li Bai's poetic talent, so he would attach great importance to what Li Bai said.From the heyday of Kaiyuan to a few years after the outbreak of the Anshi Rebellion, Gao Shi visited Liangyuan three times, visited the Yellow Crane Tower three times, visited Chang'an three times, and visited Yangzhou twice. Each time he went and left, he witnessed the turning point of everyone's life, and also profiled them.It shows the history of the Tang Dynasty from prosperity to decline.
