How big should the practice of Xiao Zhuan be, what is the specific discovery, and is it particular?

The practice of Xiao Zhuan is mainly lines. If you master the lines, the characters will naturally become big and small. You can write 8- 10cm, Yuan 'an monument, Changyuan monument, Lisi Taishan stone carving, etc. When I first started practicing. It is better to learn the inscription of Xiao Zhuan, like later generations (Wu Changshuo, Deng, etc. ).
