Shen Collection, Upper Volume Radical: Grass (cǎo) Suo Kangxi Dictionary Stroke Count: 13 Page 1033, Entry 33 Tang Rhymes (Tangyun): Pronounced suo. The same as suo. Jade Chapters (Yupian): To rub with the hands. Commentary on the Book of Odes (Shijing), Zhou South section: The Book of Character Summaries (Zilue) by Ruan Xiaoxu states: To moisten through rubbing. Poetry of Huang Tingjian: Rubbing the remnants of chrysanthemums while passing the cup. Note: According to the Collection of Rhymes (Jiyun), it is also written with a different pronunciation, though the meaning of rubbing remains the same. Investigation shows that the two characters for rubbing and kneading are based on rhyming reduplication. Both the zhi and ge rhyme categories are interrelated. If the character for rubbing is in the zhi rhyme, the pronunciation of suo is sui; if in the ge rhyme, it should be pronounced suo. Furthermore, the character suo is the same as the character for stroking; it should belong to the Hand radical. However, writers of the Tang period have already included it under the Grass radical, so it remains cross-referenced in both sections.
