Calligraphy is art, and the soul of art is change. The three horizontal lines are the same length, so they are rigid; When a horizontal line is longer than a horizontal line, it is programmed and rigid. Sanheng is like three brothers walking on the road. The order from front to back should be: second child, third child, boss. The youngest is in the middle, and the two brothers can take care of it. The boss can take care of two younger brothers in the back, and the second one is in the front, which is also a responsibility. Such three brothers are a whole connected by blood. Chinese characters are aura, life and a whole.
Square characters refer to printed Chinese characters. Chinese characters are not absolute squares, and calligraphy characters (regular script) cannot be set with squares.
