Poetry about the return of old friends after the storm.

Sun Xingyan, a scholar in the Qing Dynasty, wrote a couplet: "Don't let Spring and Autumn become a good day, it is the hardest to come with an old friend." In addition, the Tang Dynasty poet Wei You wrote a poem "A poem for a Taoist in Chuanjiashan":

It's very cold in the county today, and I suddenly think of people who live in seclusion in the mountains. You must collect firewood at Jiandi and cook some poor food when you come back.

I want to see you with a bottle of wine, so that you can get some comfort at night. But autumn leaves are full of empty mountains. Where can you find your footprints?
