This legend was first recorded in two geographical works in the Southern Song Dynasty. Wang Xiangzhi's Geodesy and Ji Sheng, Volume 55, Jinghu South Road Hengzhou, contains Yan Hui Peak "in the south of the city. Or:' Goose can't compete with Hengyang.' Or:' the peak is like a wild goose.' Zhu Mu's Yu Fang Sheng Lan is a little later than Wang Xiang's Yu Di Ji Sheng and similar to Yu Di Ji Sheng. This means that people didn't know this allusion until they read these geography books. The use of this allusion in poetry works is much earlier than that recorded in these two geography books.
The significance of this allusion mainly lies in homesickness and passing on books.
"Hengyang geese go" is the objective reality of "blocking Qiu Lai". Although "not paying attention" is a concrete manifestation of flying north and flying south, it is more important that these three words come from the hearts of the soldiers guarding the border, setting off the feelings that geese go and people don't let them go.
