This sentence came from a poem in the Tang Dynasty poet Li Bai's " Wine ". The whole sentence was: " The peacock flies southeast and the south wind knows my meaning. Who will the guest go after the three springs leave? In the rain at night, spring leeks are cut off, and new millet is cooked." The meaning of this sentence was that if the peacock flew to the southeast, the north wind would understand my feelings. Will the guests come back after the third spring? The scene of cutting spring leeks in the rain at night and cooking yellow millet was still nostalgic. This poem described how the poet missed his distant guests when he was drunk and lamented that time was short. At the same time, it also expressed the poet's nostalgia for his hometown and his loved ones.
