Yue Fei's "The River is Red·Written in My Feelings"

I am so angry that I lean on the railing, and the misty rain stops. Looking up, looking up to the sky and roaring, with strong feelings. Thirty years of fame and dust, eight thousand miles of clouds and moon. Don't wait any longer. The young man's head will turn gray, and it will be so sad! (Column link: Lan)

Jingkang’s shame has not yet snowed. The hatred of the ministers, when will it be destroyed! Driving a long car, crossing the gap in Helan Mountain. The ambition is to eat the meat of Huns when they are hungry, and to drink the blood of Huns when they are thirsty. Waiting to start over, clean up the old mountains and rivers, and face the sky. (The first work of ambition: the strong man; the first work of the mountain lack: Shanque)
