What progress has been made in the history of calligraphy of Shiqingzi in Qin cemetery?

The inscription on the stone chime of Qin cemetery was written in the fourth year of Qin Jinggong in the late Spring and Autumn Period (574 BC). It was also found in Fengxiang County, Shaanxi Province, where Shi Guwen was first discovered, and was unearthed in the No.1 Tomb of Qin Gong. The stone chime is delicate in texture, smooth as a mirror and pleasant in tone. More than 20 pieces of stone chimes and fragments of stone chimes of different sizes are regarded as braids. Every Qing dynasty has an inscription, and every sentence rhymes neatly. Because the stone is exquisite and recently unearthed (1986), it is carved, and looks fresh and atmospheric compared with muddy and dignified Shi Guwen. Among them, the words "Si, Fang, Gao, Yu, Si, Ping and Ri" are not obviously different from those in Biography. Its linear rigidity, upright structure and slender posture are closer to Xiao Zhuan than Shi Guwen. This is a group of works that are more forward than Shi Guwen in the history of calligraphy, towards simplicity, standardization and the ideal of Qin people.
