Si Collection, Middle Volume Radical: Fire (huǒ) Character: Cui Kangxi stroke count: 15 Page 680, Entry 30 Compendium of Rhymes (Jiyun): Pronounced sui (level tone). It refers to the soot and dust from smoke. Note: In the Categorized Dictionary of Characters (Leipian), it is also pronounced hu (entering tone) and wu (entering tone). The Compendium of Rhymes only attributes these two pronunciations to the character, but the character Cui only has the single pronunciation of the level tone. The Categorized Dictionary of Characters is incorrect in this regard.
