Mao Collection, Middle Volume Radical: Hand (shǒu) Kangxi strokes: 15 Page 449, Entry 09 Pronounced sa. To strike with the side of the hand. Gongyang Commentary (Gongyang Zhuan), 12th year of Duke Zhuang: Song Wan struck Chumu with the side of his hand. Commentary: Striking with the side of the hand is called sa. Another theory suggests it means to wipe away or destroy. Epitaph for Meng Jiao by Han Yu: Only he indulged greatly in his prose, and was at odds with the world. Commentary: Meaning to wipe out or extinguish. In ancient times, it was used interchangeably with the term meaning to kill off. It also carries the meaning of waving away or scattering. Also pronounced sha. This also means to strike. Also pronounced xue. The meaning is the same. Also pronounced sa (rising tone). To shake or rouse. Also pronounced xie. Note: In the Record of Trades (Kaogong Ji), section on Wheelwrights, it is written that when the rim is secured, it is fixed without the need for a wedge. The commentary says the wedge is a wooden peg; people of the Shu region call a wedge a peg. According to the Explanatory Text, the pronunciation is xie, using the wood radical, not the hand radical.
