A poem that begins with the word Tianzi.

How long is heaven and earth and how short is human nature. -Cao Cao's world is full of troops, and the mountains and rivers are sad. -Du Fu, even in this world, is a heroic spirit, which has existed and ruled for thousands of years. -Liu Yuxi is upright in heaven and earth, in many ways. -Wen Tianxiang Tianhe hangs green water, showing nine hibiscus. -Li Bai Three zhangs of snow in Tianshan Mountain is a long journey! -Li Qingjiang moonlight during the day, seagulls know when it is calm. -Li Bai is cold and the mountains are clean, and the long river is in a hurry. -Wang Wei, everlasting, everlasting; One day both will end, and this endless sadness will last forever. -Bai Juyi
