Allusions are folded into willows.

The word "broken willow" means "farewell";

In ancient China, once relatives and friends were separated, people who saw them off always folded a wicker for travelers. The word "broken willow" means "farewell forever". The custom of "sending willow" in China was first seen in Xiaoya. Cai Wei: "I have been there, Yangliuyiyi; Today I think it's raining. " In ancient times, willow was also called Xiao Yang or Liu Yang. Because "Liu" and "Liu" are homophonic, they can mean to stay. Giving a willow tree as a parting gift means that we are inseparable and reluctant to part. There is a song "Folding Yang Liuzhi" in Yuefu in the Northern Dynasties, and the lyrics are: "If you don't catch the whip when you get on the horse, you will hit Yang Liuzhi instead. Dismount and play the flute, worrying about killing guests. "

Li Bai's "Willow Leaves Every Year, Baling Mourning Farewell" illustrates such a custom: in ancient times, there were ten-mile long dikes on both sides of Chang 'an Baqiao Bridge, and many people who walked from Chang 'an East came here to bid farewell and fold willow branches for their relatives. Bai Juyi's "Qing Men Liu" "Don't go near Doumen, long folds reduce the spring breeze." Yu's "Folding Willow" "There are flowers hanging at the farewell party, and the willow is folded in smoke." "Farewell by folding willows" contains a good wish for friends that spring will last forever, and it also means that relatives leave their hometown like willow branches, hoping to take root and sprout in a new place soon, as if willow branches can blossom everywhere.

When people leave, they will also send their love when they miss their loved ones and old friends. The word "folding willow" also means "nostalgia". Zhang Jiuling "slim willow, hold this as a lover"; Li Bai "climbed the pole to fold the spring scenery and sent it far to Long Ting"; Li Bai's "Xuancheng sent Liu's deputy envoy to Qin" is "no acacia, broken" Li Bai's "Whispering flute in Los Angeles on a spring night": "The sound of the flute flies in the darkness and the spring breeze permeates Los Angeles. Who can't afford to be homesick when they hear the willow break in this nocturne? "
