A poem describing loyalty: Fan Zhongyan's "Yueyang Tower": Worry about the world first, and then enjoy the world. Lu You's Wind and Rain on November 4th: Sleeping in a lonely village, not feeling sorry for yourself, thinking about defending our country and singing about coal. Author: Yu Qian digs chaos to get Wu Jin, and he has the deepest meaning of storing yang. The fire rekindled into spring, and the furnace shone all night. Ding yiyuan relies on power and pays attention to the stone after death. I hope that all people will warm their hearts and go out of the mountains tirelessly. Lime singing-Yu Qian chisels out the deep mountains, and if the fire burns idle. Don't be afraid of being smashed to pieces, leaving innocence in the world.
