Su Shi's "Niannujiao Chibi Nostalgia" is known as the masterpiece of "Eternal Farewell", which is the most widely circulated and influential work in Song Ci, and also the most outstanding representative of bold and unconstrained Ci. Written in July of the fifth year of Yuanfeng (1082), Su Shi was demoted to Huangzhou.

When I visited the former site of Chibi outside Huang Feng. Su Shi is 47 years old this year. Not only did he fail in his career, but he was also punished by Huangzhou.

This word feels ancient and modern, vigorous and desolate, majestic and high-spirited, with both emotional and sentimental colors.

But the sentimental color at the end of the article can't hide the heroic style of the whole word. Before Su Shi, the perfect combination of the magnificence of mountains and the heroic achievements in ci never appeared successfully. Therefore, this poem Niannujiao Chibi Nostalgia has always been regarded as the representative work of Su Shi's bold and unconstrained ci.
