Li Bai and Du Fu, Meng Haoran, Wang Lun, Wang Changling, Gao Shi, Yuan Danqiu, etc. Met because of poetry and stayed together because of love, but they also faced separation and choices in troubled times. Who knows Li Bai best? Who can understand the loneliness behind his wildness, the joy and regret in his poems? Those friendships and perseverance hidden in the pen and ink, those figures under the fireworks of the prosperous Tang Dynasty, those joys and losses, perseverance and separation, have all become touching footnotes to the prosperous Tang Dynasty.
