Shu (pinyin: shù) is a first-class Chinese standard Chinese character and commonly used word, which first appeared in Shang Dynasty. "Tree" is a pictophonetic character, and the ancient shape follows the wood. The original meaning is planting, and it is extended to the floorboard of establishment, cultivation and woody plants. The characters of the Shang Dynasty, from wood to wood, are like planting trees by hand, which is the first character of a tree. The spring and autumn characters are marked with the sound of "bean" and set as glyphs. The regular script structure in Shuowen is the same as the font, but influenced by later characters, the word "you" has been mistaken for "inch".
During the Warring States Period, the characters changed from "Qian" to "Yi", which was a common phenomenon in ancient China characters. The word "Mu" in Biography is a simplified word, and its left half is the same as the word "Bo" (Bo is the initial of "drum"). The word "you" was changed to "inch", which completely lost the meaning of "planting wood", so the word "tree" was added next to "wood" and "tree" was written in simplified characters.

The original meaning of "tree" is planting, while Shuowen: "tree is the general name of planting", and Guangya explained that "tree is also planting", which means establishing. Guang Yun's rhyme: "Trees stand upright", also extended to the floorboard of woody plants. Guang Yun's rhyme: "Trees always have the same name".
