What is Su Dongpo's running script, which is called the third running script in the world?

Huangzhou Cold Food Poetry Post has a great influence in the history of calligraphy, which is called "the third running script in the world" and is also a leader in Su Shi's calligraphy works. It is known as "the third running script in the world" for the following reasons.

1, Huangzhou cold food poem post was endowed with Su Shi and his deep affection. This is a poem to send a revival, and it is a sigh of life caused by Su Shi's relegation to Huangzhou for three years. The poem is desolate and affectionate, expressing Su Shi's melancholy and lonely mood at this time. The calligraphy of this poem is produced in this mood and situation. The whole calligraphy is full of ups and downs, radiant and unrestrained, and there is no shortage of pens.

2, ups and downs throughout, rapid and steady, incisively and vividly, in one go. Su Shi put the changes of artistic conception and emotion in his poems in the changes of stippling lines, either before or after, changing and changing, breaking with the trend, and being natural. Its words are also strange, big or small, sparse or dense, light or heavy, wide or narrow, uneven, arbitrary and strange, and varied. As Huang Tingjian wrote after this poem: "This book was also written by Yan, Yang and Li Xitai, which is not necessarily the same as those who tried to restore Dongpo.
