It may be hanging needles or hanging.

Xu Zi was erected with a garter. Cao has a hanging needle seal, which is a kind of writing based on Xiao seal. It's called garter stitch, but it's still different from Xiao Yin. Hanging a needle means that the pen draws vertically and hangs like a steel needle. Exposing and hanging is a kind of writing method of direct painting, and it is also a kind of writing method created by Cao Xichuang. Its essence is Xiao Zhuan. The place where the pen is hung vertically is like dew, which can't be hung off, so it is called hanging dew. Different from "hanging a needle", Feng Wu's calligraphy is saying: "If you want to shrink the front, draw the front and stretch the front, you must be equal from beginning to end. But sharp ears. Don't be like a mouse's tail. According to the ancients, there is only one way to expose it. The garter needle starts with the word' year' in Lanting, and later generations think it is the law. "

The difference between vertical suspension and vertical suspension

There is a big difference between the two. Sun's Book Score in the Tang Dynasty said: "Look at the difference between a husband hanging a needle and a hanging needle." Vertical painting is the most widely used in basic strokes, which can be divided into vertical painting and vertical painting. The morphological difference between vertical painting and vertical painting lies in the end of strokes. One is called vertical painting, and the other is called vertical painting.

In practical application, hanging is more widely used than hanging. Generally, hanging vertical is used for short vertical, long vertical and even vertical paintings of various lengths, but hanging vertical is different. It cannot be used in the position where strokes are connected or in some fixed radicals. More specifically, the hanging dew vertical can replace the hanging needle vertical in most cases! Viewed from the side, vertical hanging dew is more widely used.
