What stages did Sui and Tang calligraphy go through?

(1) Sui Dynasty to early Tang Dynasty.

Sui unified China and accepted the culture and art of the Southern and Northern Dynasties. At the beginning of the Tang Dynasty, politics flourished, and calligraphy gradually emerged from the legacy of the Six Dynasties and took on a new attitude. In the early Tang Dynasty, regular script was the mainstream, and its overall feature was strict and orderly structure.

(2) In the middle of the Tang Dynasty.

Calligraphy in the prosperous Tang Dynasty, like the social form at that time, pursued a romantic way of getting carried away. Such as "Zhang Dian Drunk" (Zhang Xu, Huai Su), Li Yong's running script. In the middle Tang Dynasty, regular script made a new breakthrough. Yan Zhenqing, as the representative, laid the standard of regular script, set an example and became orthodox. At this point, China's calligraphy style has been completely determined.

(3) The legacy of the Tang Dynasty existed in the late Tang Dynasty and the Five Dynasties.

1907, Zhu Quanzhong, the separatist, destroyed the Tang Dynasty and established the Houliang, from which the later Tang Dynasty, the later Jin Dynasty, the later Han Dynasty and the later Zhou Dynasty were called the Five Dynasties. Due to the weakness and disorder of the country, culture and art are also declining. Although the art of calligraphy continued after the end of the Tang Dynasty, due to the influence of war and fire, it formed a general trend of decline. During the Five Dynasties, Yang Ningshi's calligraphy was praised. In the five dynasties when calligraphy declined, his calligraphy was the mainstay. There are also outstanding calligraphers, such as Li Yu and Yan Xiu. At this point, the upright and rigorous style of calligraphy in the Tang Dynasty came to an end, and then the "four schools" in the Northern Song Dynasty followed suit and set off a new wave of the times.
