"Meeting a friend again in the fallen petal season" is the ending sentence of On Meeting Li Guinian South of the Yangtze, a ancient poem written by Du Fu, a poet in the Tang Dynasty. As the curator of this exhibition, Yang Wei took this sentence, which expresses the pleasure of meeting an old friend, as the theme. Yang Wei said in the preface of this exhibition: this is a poem about reencountering and recollecting of the past. The good old days are easily recalled by simple words, such as "Prince Qi's mansion" and "Cuijiu's home" in the poem, because old friends have close relationship and shared experience. When meeting an old friend, a short sentence can bring out every drop in the river of the past, creating the spindrift of emotion.
