Wu Collection, Upper Volume Radical: Jade (yù) 玊 Kangxi stroke count: 5 Page 727, Entry 01 Correction of Rhymes (Zheng yun) states that the characters for jade (yù) and this character (sù) are distinct. When the dot is written below the stroke, it is the character for precious jade. When the dot is written in the middle of the stroke, it is the character for this entry, pronounced su. This character refers to an artisan who carves jade. It also refers to decayed or ruined jade. It is also the name of a state and a surname. In common script, this character and the character for jade are often confused. Correct Meaning (Zheng zi tong) states that in the Rites of Zhou (Zhouli), the six types of artisans—earth workers, metal workers, wood workers, stone workers, animal workers, and grass workers—are all called artisans. Someone who carves jade is called a jade artisan, just as someone who whittles wood is called a wood artisan. One should name them according to their craft and there is no need to create an additional character to refer to a jade carver, nor is there a need to pronounce this character as su or xiu. Contemporary jade artisans all write this as the standard character for jade rather than this character, which further shows that this character is redundant. Although it is recorded in the Correction of Rhymes (Zheng yun), later generations do not follow or adopt it.
