Thick ink is the most common way to use ink in writing. With thick ink, the ink is black and shiny, which can make the spirit flourish and solemn, which is called "strong for its work". But not too thick, "too thick will delay writing."
Second, light ink
Compared with thick ink, light ink is slightly gray in color, well used and not lacking in spirit. It can produce elegant and distant taste, and has a knee-high aesthetic feeling, which is called "light desire to produce flowers". But it should not be too light, which will lead to thinness and mental injury.
Third, dry ink
Dry ink means that there is less water in the painting and sometimes it is white. In Jiang Baishi's sequel, there is a saying that "the ink for writing needs to be dried, but not too dry". When it is dry, the pen is dry, and when it is dry, it dies. Therefore, dry ink must be used to prevent dryness, listlessness and poor blood circulation.
Fourth, wet ink
Compared with dry ink, wet ink means that stippling contains more water. Wet ink drips with the pen, and stippling is rich and bold, but we should prevent "ink pig", that is, ink without pen and bone.
Five, thirsty pen
Thirsty pen refers to writing with less ink, and there is a white dry pen between words, so it is also called "dry pen". Liu Qingxi wrote in "The Outline of Arts and Books": "Cursive writing is thirsty for writing, based on flying white. Using a thirsty pen is clear and serious, not starting with a thirsty pen. You must start with every word before the pen and the pen can be hooked by the center. " It can be seen that cursive writing often uses thirsty pens, which seems vigorous, but it is actually dangerous. There is a poem in Li Rihua's Tian Ji in the Ming Dynasty: "The book is so thirsty that it is difficult to control. Hanging vines on the cliff, the hole is shocking. "
