Tell me about the difference between hanging a needle vertically and hanging it vertically in calligraphy.

The hidden front method, exposed front method, starting pole and running pole are all the same as those hanging vertically. When the length is close, the strokes are slowly raised, and the speed is required to be approximately skimmed, but slower than skimming. Because the hanging needle is vertical and unstable like a mainstay. If the front is too fast, it may skew and float. The most difficult thing about garters is to write impartially, like an iron column standing upright.
