The main points of hard pen calligraphy are: first, the strokes should be straight and not staggered; The second is to be in place and not give up halfway; Third, we must persevere and not do it at will. It takes three days to fish and two days to dry the net to practice good words. Fourth, we should pay attention to the structure of words, and we can't write one word into two words; Fifth, writing and sitting posture should be standardized.
If you want to write well, you can't just rely on one or two efforts, you must persevere.
