The expression of "Sunset Snow in Qian Shan" is that at night, snow and ice cover the endless mountain peaks. From "Fish and Qiu Yan Ci", it was written by Yuan Haowen, a writer in the Jin Dynasty. This word was written by a poet who was moved by the death of a wild goose and expressed his grief for the martyrs.
Year means year. Generally refers to time. From Historical Records Biography of Hengshan Mountain in Huainan: "If you bend your strength and relax, you can still prolong your life."
Trouble, worry, sadness. From Historical Records Biography of Qu Yuan and Jia Sheng: "Qu Ping's sick king happened to listen to it, but it was flattering to cover up the Ming Dynasty, and the evil songs harmed the public. Fang Zhengzhi could not tolerate it, so he wrote Li Sao with sad Zen."
