What are the artistic features of cold food poems in calligraphy?

Cold Food Poem Post is unique and steep, and the pen is more vigorous and ups and downs. The font Fiona Fang is long and short, and the word potential is also measured. The first of these two poems begins with a slow pen, which is similar to his original work. The brushwork of "It rains again this year, playing the flute in February, and the bedroom of begonia is covered with mud and sweat" is graceful and vigorous, which reflects the poet's lingering affection. The brushwork of the second poem is more radical than the previous one, to the point of "knowing that it is cold food, but seeing a bird with a piece of paper in its mouth", which also reflects the poet's grief and indignation that "I want to cry, but I can't afford to paint the poor". Looking at his calligraphy, there is a desolate feeling between the lines. In the expression of emotion, people compare it with Wang Youjun's Preface to Lanting and Lu Gong's Sacrifice to My Nephew.
