The background of this word is Xin Qiji. At the end of June (1203), Song Ningzong Jiatai was appointed as the magistrate of Shaoxing and the peace envoy of eastern Zhejiang. The following spring and March, he was reassigned to Zhenjiang as a magistrate. At that time, Zhenjiang was once a place where heroes used their troops and made outstanding achievements in history, and it became an important line of defense against the Jin people. Every time Xin Qiji goes to Jingkou (now Zhenjiang), he will come to Gubei Pavilion, which is located above the city wall and near the bank of the Yangtze River, where he can enjoy the scenery and reminisce about the past.
