Du Fu's "Water Threshold to Send Heart" "Fish comes out in the drizzle, and Yan is inclined in the breeze."
Wild geese are unrestrained, homesick and miss their loved ones. For example, Fan Zhongyan's "The Fisherman is proud of Qiu Si" "The scenery in Qiu Lai is different, and Hengyang geese don't pay attention."
Li Qingzhao's "A Piece of Plum" "Whoever sends a brocade book, the geese will return to the West Building in the next month."
Wen Tingyun's "Yao Sefen" "The geese are far louder than Xiaoxiang, and the twelfth floor speaks for itself."
Another important meaning of geese is letters, the most obvious embodiment of which is Wang Wan's "The next berth on Beibao Mountain can finally send my emissary geese home to Luoyang".
Well, happy new year!
