Cheng's cursive script is as shown below:

Cheng (Pinyin: chéng, shèng) is a commonly used character in modern Chinese. The earliest glyph can be seen in the oracle bone inscriptions of the Shang Dynasty. Cheng is a Chinese character that resembles a person on a tree. The original meaning of "Cheng" is to climb up and read "cheng". By extension, it refers to riding in a car or boat. Being in a car is called "charging", and being on a boat is called "chuan". "Cheng" also means to adapt and take advantage of it, such as: riding the wind and waves, taking advantage of a weak point.

Knowledge words. In the oracle bone inscriptions of the Shang Dynasty (Figure 1), the upper part is "big" (referring to people), and the lower part is "木" (referring to trees). The man was in the tree, high above the ground. The original meaning is to climb up; once the image is said to be like a person riding on a tree, the original meaning is to ride or sit. In order to highlight the meaning of people stepping on trees, the characters of the Western Zhou Dynasty added two "Zhi" (foot) characters at the bottom of the big character.

The writings of the Warring States period have been even more corrupted. Except for the characters of the Qin Dynasty, most of them have changed from "mu" to "ji". In addition, the two "stops" originally marked at the bottom of "大" are often changed from "大" to "大". "It looks like the two arms of a person are directly connected. The character "?" in "Ji Yun" in Chu characters is derived from "Che", which is a differentiated character for "成", and the meaning of the character remains unchanged. The official script of the Han Dynasty followed the character shapes of the Qin Dynasty and developed in the direction of convenience for writing.

Regular script succeeds Xiaozhuan and official script. In ancient times, there were three main writing methods: Cheng, Cheng and Chu. "椉" directly reflects the structure of Xiaozhuan; "成" means the person above it and the wood below it are written together, and the left and right feet become the character "北"; "成" combines the strokes on the basis of "椉" formed. The "First Batch Variant Character Collection List" defines "成" as the orthographic character, and "成" and "椉" as variant characters.
