Li, a commonly used Chinese word, is pronounced lǐ, which was first seen in Oracle Bone Inscriptions or Jinwen. Its original meaning is a deciduous tree with white flowers in spring and sweet and sour fruits in summer. Shuowen Jiezi is regarded as "the fruit of a tree", with "wood" as the square and "zi" as the phonetic side. Therefore, the fruit is sweet and sour, which can relieve difficulties and fatigue. For ancient travelers who traveled long distances on foot, it was almost a necessary condolence item, so it became synonymous with travel preparation in travel bags. Today it is mainly used as a surname.

Secondly, it is considered that the earliest "Li", as shown in Figure (a), is an ancient bronze inscription in the seal cutting of the Warring States period, with the word "Zi" under the wood. However, the "Li" of "Chen Zan" in Figure (2) during the Warring States Period was the left "Zi" and the right "Mu", not today's picture; The philologist Shang Chengzuo said that this is the ancient Chinese character Zi written by Sang Zi, but it didn't appear until Qin Zhuan, so there is no way to verify it. Later, the seal script of the Qin Dynasty evolved into the characters in Figure (c), and the word "Li" in Figure (d) only changed the fork-shaped word "Mu" in the upper part of the seal script into the word "Zi", and removed the circle of the word "Zi" in the lower part of the seal script to write the word "Zi".
