"Calligraphy Treasure" level.
Song Huizong's running script work "Cai Xing's Imperial Scroll" can be called a transcendent existence at the level of "treasure of calligraphy".
Zhao Ji, Emperor Huizong of the Song Dynasty, wrote "Cai Xing's Imperial Order" in running script. This volume was an imperial edict issued by Emperor Huizong of the Song Dynasty not allowing Cai Xing to resign from the post of leading the province. The lines of this edict are white and sparse, and the strokes are slender. The ink rhyme is smooth, free and fresh, like the drifting vines and willows.
