The explanation of "Time is like a river, and there are many heroes in history" is that time is like a big wave, and those who leave their names in history are outstanding talents. The source of this poem comes from the Song Dynasty writer Ouyang Xiu's Langtaosha. It is a little word that cherishes and misses spring and says goodbye when you are hurt, expressing the sigh of impermanence in life.
Ouyang Xiu
Ouyang Xiu was the earliest literary leader who created a generation of literary style in the literary history of Song Dynasty. He, Han Yu, Liu Zongyuan, Su Shi, Su Xun, Su Zhe, Wang Anshi and Ceng Gong are also called "eight masters of Tang and Song Dynasties", and Han Yu, Liu Zongyuan and Su Shi are also called "four masters of literature through the ages". He led the poetry innovation movement in the Northern Song Dynasty, and inherited and developed Han Yu's ancient prose theory.
His high achievements in prose creation and his correct theory of ancient prose complement each other, thus creating a generation of writing style. Ouyang Xiu not only changed the style of writing, but also innovated the style of poetry. He has also made great achievements in historiography. He once majored in the Book of the New Tang Dynasty and wrote the History of the New Five Dynasties alone. There is a collection of Ouyang Wenzhong's works.
