Special explanation:
Zhuān (Pinyin: Zhuā n) is a first-class standard Chinese character (commonly used word). The word first appeared in Shang Oracle Bone Inscriptions and Shang inscriptions? Its ancient glyph is like a hand shaking a spindle and winding silk around it.
The original meaning should be rotation, and then the original meaning should be changed to "turn". In rotor spinning, scattered fibers are concentrated in one bundle, so "specialization" extends the meaning of concentration and singleness. From the meaning of single-mindedness to exclusive mastery and control, to arbitrariness.
