For advice, Liu Ti calligraphy has been around for six years. Encountered a bottleneck.

It has begun to take shape and is very good. Work harder on the pen and structure. Compared with Yan Heou, Liu's strokes are thin, hard and straight, with bones and muscles. Writing the same strokes, there are more internal movements, and many seemingly exposed strokes are hidden. The structure is as follows: tight inside and loose outside, tight at the top and loose at the bottom, tight at the front and loose at the back, tight at the left and loose at the right. Read more posts, ponder more and practice more. I wish you success!
