My father put up red couplets on the doors and red paper-cutting on the windows.
我父亲在门上贴了红色的对联,在窗户上贴了红色的剪纸。
They paste up Spring Festival couplets, greeting the New Year and saying goodbye to the old year.
他们贴春联,辞旧迎新。
Translated by Xu Yuanchong, this famous poem, with four couplets, was written by Du Fu (712-770, Tang Dynasty) when he was living and farming in Chengdu.
