This couplet, ?Cold weather delays the flowering trees; warmth moistens the fields for ploughing,? was written by the Qianlong Emperor for the Sui'an Room at the Daxinzhuang traveling palace in Sanhe. Qianlong visited the Yanjiao palace area many times and left behind numerous poems and couplets there. This inscription expresses the idea that cold weather hinders the growth of flowers and trees, while a warm climate benefits agricultural development.
