Theoretically it is indeed too complicated. In fact, as the saying goes, you will know that the tip joint is in small regular script, but some words in pen calligraphy are particularly thick. When the words are thick, you can draw them naturally one by one. When written, the character will become larger, but it is not big, ugly, or loose. In this case, the method used is sharp connection, that is, virtual connection. Use a virtual pen, and you can also use dots to replace various strokes such as horizontal and vertical strokes, but the most important thing here is to connect the meaning. In fact, every one of us is using point joints when writing, but we just don’t know it. Think about it when you write running script, do you use it frequently? Or sometimes the thick characters are passed by just a hook, and the stroke of the pen is the point joint. . It will be easier to understand if you think about it this way. Difficult things are easy to understand, but common and easy things are often the most difficult to understand.
