Li Bai's four-character poem Shangjietie is the only original calligraphy handed down by Li Bai, which is a national first-class cultural relic and is called "first-class".
The 25 words of Shangjietie not only summarize the majestic momentum and long-standing water of Wuwangshan, but also express the author's admiration for his works by praising Sima Chengzhen. The whole volume is vigorous and elegant, with the pen freely placed vertically, fast and healthy, and the statutes are eclectic, just like Li Bai's bold and elegant poetic style. The whole paste structure is also uneven, ups and downs, looking forward to family and endless fun.
