Xiao Zhuan (Qin Zhuan) is a simplified character evolved from Da Zhuan, and it is also the product of large-scale standardization of characters by administrative means for the first time in the history of China.
Xiao Zhuan was popular in China until the end of the Western Han Dynasty, and was gradually replaced by official script. After Qin Shihuang destroyed the Six Kingdoms, Qin's Biography was taken as the standard to unify the writing. China characters developed to the stage of Xiao Zhuan, and gradually began to finalize the design (outline, strokes, structure), and the pictographic meaning weakened, making the characters more symbolic and reducing the confusion and difficulties in writing and reading.
