(1), "Jin Fang Gu Zhuo", official script evolved from simplified Chinese seal script. The circle of seal script has been changed to a square fold, so there is a saying that "seal script is a square", official script is an ancient script, and "Jin Fang Gu Zhuo" tells the general picture of official script.
(2) "There must be a three-fold pen at the head of a silkworm and a goose's tail" refers to the unique horizontal painting of official script-the modeling of wave horizontal painting (that is, picking up the foot horizontal painting) and the writing steps of official script strokes. When writing a wavy cross, first "hide the front and reverse the front" to the left and then turn the pen to the right. Shaped like a silkworm head; Then lift the pen slightly to make it move from the center to the right, that is, "flat out"; Finally, when writing feet, the pen tip is pressed down, slowly lifted and picked out to the right. It is shaped like the tail of a wild goose. Generally, pens are closed before exposure, but some are slowly closed before exposure. When writing a cross, you should pay attention to the use of "quotation". In this way, the strokes are natural. "The pen must be folded three times" refers to the three steps of putting down the pen, writing the pen and collecting the pen, also known as the "three-fold method". It is the basic method to use a pen for official script without sweeping or slipping.
(3) "Gooses don't fly in pairs, silkworms don't have two colors", which means that in the words of an official script, don't repeat strokes. If a word has two or more horizontal strokes, only one stroke can be written as a wave, and the other stroke can be written as a horizontal stroke, which is called "flying geese don't fly together"; "Silkworm has no two colors" means that the writing of the silkworm head is basically the same, but the shape of the silkworm head can be slightly changed.
(4) Because the shape of the official script is horizontal, many strokes are symmetrically unfolded, especially the combination of left and right strokes, which obviously increases the vivid feeling.
