"Out of trouble? One (Wang Changling): The moon passed through Qin, and the Long March people did not return. If Wei Qing, who attacked Longcheng, and Li Guang, the flying general, were alive today, the Huns would not be allowed to go south to spend their horses in Yinshan.

Liangzhou Ci (Wang Zhihuan): The Yellow River is far above the white clouds, and there is an isolated city-Wan Ren. Why use the elegy of willow to complain about the delay of spring, old Yumenguan, a spring breeze is not blowing!

Liangzhou words? One (William Wang): A glass of sparkling wine. If you want to drink pipa, you should hurry at once. Drunk lying on the battlefield, you don't laugh, there have been several wars in ancient times.

Listening to the Xiao in the Bunker (Gao Shi): The snow is clear, the horses are grazing in the lake field, and the Xiao is guarding the building in the moonlight. Excuse me, where did the plum blossom fall? The wind blew all over the mountain overnight.
