I don't know if it's a poem but my ancestors from Hainan island passed down this list of words to use for each generation. So all the men in m family have names following this order.

FamilyName WordFromList RealName

and people address us as WordFromListRealName.

Apparently, this list is also shared with other Hainanese descendants that share the Heng family name (maybe we have a shared lineage?) because my relatives have a habit of looking in the obituaries for fellow dead Hengs and to see how far along the list they've come.

I don't intend to follow this tradition.
