The brushwork of calligraphy in the Tang Dynasty had a great influence on later generations. It is precisely because of its strict laws and regulations that the innovation of calligraphy was imprisoned after the Tang Dynasty.
In fact, the retro style of Zhao Meng era is to restore the brushwork of Wei and Jin Dynasties. It's just a pity that it didn't achieve its goal, but it revived and developed the brushwork of the Tang Dynasty. In fact, the calligraphy of the Ming Dynasty is very independent, that is, it is honestly inherited, but the foundation can be seen.
It was not until the Qing Dynasty that a group of calligraphers, such as Fu Qingzhu, Jin Nong and Kang Youwei, really put the restoration of the Wei and Jin Dynasties steles into place. The brushwork in Wei and Jin dynasties is the same as that in Weibei. Therefore, the innovation of calligraphy needs to return to the source of brushwork in Wei and Jin Dynasties, so as to inherit the authentic traditional brushwork, and then carry forward and innovate.
