Shen Collection, Upper Volume Radical: Grass (cǎo) Di Kangxi strokes: 11 Page 1022, Entry 19 According to the Collection of Rhymes (Jiyun) and the Correct Rhymes (Zhengyun), this character is identical to the character meaning "together." It is also a type of compound surname. According to the Comprehensive Treatise on Clans and Lineages (Tongzhi Shizu Lue), the Bu Di clan belongs to the Zi surname. The Corrected Dictionary of Characters (Zhengzitong) states that the Collection of Sea of Characters (Pianhai) incorrectly treats this as a variant of the character meaning "sequence," which is incorrect. In the Collection of Rhymes (Yunhui), the character for "sequence" has the meaning of "but," and is also written as the character for "younger brother." The Collection of Characters (Zihui) writes it as this character, which is erroneous.
