Because in the Anshi Rebellion, Gao Shi and Li Bai worked for two rival parties. As a result, Gao Shi was lucky and won the war, but Li Bai was exiled. Du Fu was deeply shocked when he learned that, so the three of them stopped seeing each other.

Gao Shi is a representative of frontier poets. As a frontier poet, he is also a person who likes to make friends with world heroes. Later, Li Bai and Du Fu met Gao Shi, and Gao Shi and Li Bai chatted happily and became good friends. Because Li Bai was the most famous of the three of them at that time, Gao Shi and Du Fu often stayed with Li Bai, and the three of them toasted together. They like drinking, watching songs and dances and tasting poems. They talked and laughed, and their lives were very happy.

Later, Gao Shi was admitted to Jinshi, and with the opportunity to enter the officialdom, his career was smooth. Unfortunately, when the Anshi Rebellion broke out, Gao Shi had to flee with Tang Xuanzong. At that time, Emperor Xuanzong of the Tang Dynasty commanded at will and handed over the relieving power to ambitious Li Lin. He rebelled after taking control of the military power.

Tang Suzong was very anxious about this matter, so he called Gao Shi and others to discuss countermeasures. Gao Shi told Tang Suzong that Li Lin would fail, and Tang Suzong was glad to give it to him. At that time, Gao Shi probably didn't know that Li Linjun was assisted by Li Bai. It will be over soon. Gao Shi defeated Li Lin and Li Bai was exiled. From then on, Li Bai's life was hopeless. Du Fu was very sad after hearing the news. He has nothing to do with Gao Shi anymore.

In this way, the three of them are strangers, because they are all their own masters and must do their best for the future. It can only be said that Li Bai's political view is not high and powerful, so it will lead to such a situation.
