The scenery is different when autumn comes in the fortress, but the geese in Hengyang leave without paying attention. Sounds ring out from all sides, thousands of miles away, long smoke sets, the sun sets, and the lonely city closes.

A glass of wine can lead to a home thousands of miles away. The Qiang pipes are covered with frost, people can't sleep, and the general's hair is white and his husband is in tears.
