Second, the length is surprisingly thin in the middle. In fact, many regular scripts, such as Liu Ti and Ou Ti, are thin in the middle and thick at both ends, but the middle of the long horizontal is much thinner than the middle of the long horizontal. Because Yan's horizontal pen itself is very heavy, the middle is particularly thin, so I thought of using thin to describe Yan's long horizontal characteristics. Third, the infusion needle is vertical, and the middle belly is raised. Although the face is vertical, it also has its own characteristics, but it has never been clear that the garter st is vertical. Look carefully at the length of the needle hanging on your face. The pen is not as thick as the middle. This is the characteristic of the face. In the future, as long as you see the hanging needle in the middle abdomen, you can definitely judge that it is a face.
