Despite this feeling less like a family history write-up, and more like a school/research assignment, here we go...
Adding on to what Henry responded with:1. Is a Lee family poem from Hoiping the same as one from Toisan or Heungshan?- tl;dr: Maybe.
— family/generation poems are (1) surname dependent, (2) lineage dependent*
— lineages might cluster in a particular district/region, but may also have branches that have moved between/among/back-and-forth between districts
*: many surnames claim descent from a single ancestor that migrated into the province; some surnames, however, may have multiple in-migrations, which mean that there might be more than a single "provincial" ancestor.
— within Toisan itself, for the LEEs:
—— there are three in-migrating ancestors that are not overtly related;
—— the majority of all LEEs in Toisan descend from a single ancestor;
—— there are multiple generation poems for these majority related LEEs, based on which of the 4 sons of that primary in-migrating ancestor;
—— within these branches, there can be variation in one or two of the generations, because the family underwent some sort of bad-luck/upheaval;
—— the assumption that there is a 1:1 relationship with village:surname usually holds true for most villages in Toisan and Hoiping
(Yanping, Sunwui, Chungsan, and many of the Saam-yap districts often have higher ratios of multiple-surnames to a single-village)
—— even if there is a 1:1 relationship between village and surname, some villages might have a single lineage, while others might have multiple lineages of the same surname (because of migrations of other lineages to a friendly related lineage).
2. I've been criticized for calling it a generation family poem instead of just a family poem. What is the proper term?排歌 paai-go
班派 baan-paai
(穆字 muk-zi, 字輩 zi-bui, 班次 baan-ci usually refer to the componential aspect)
In English, the preferred term is "generation poem," because the characters of the poem are used one after another to indicate (1) senior-junior relationship between generations and (2) who are in the same generation, cf
en.wikipedia.org/wiki/Generation_name; many want to emphasize that it's individual to a 'family' in an extremely myopic scope, because they think their own "family" (often conflated with "surname/clan") will share it.
3. Who writes a family's poem?
As Henry has mentioned, usually family elders (usually the intersection of those that manage the lineage registries and are literate, for which overlap is of high degree).
UNLIKE the current situation in the diaspora, where clan lineages rarely know other related branches beyond their immediate families, clan networks were much more prominent. This means that if a single village is relatively unfamiliar with the traditions or have lower literacy rates, there would be neighboring related villages that would be used for consult and reference.
4. What qualifications does the writer need to have?
Usually, this is done by committee, rather than a single person.
In the diaspora, however, it often falls to a single literate/knowledgeable person to try and keep things going, since there's less contact with the clan at-large.
Committee members would have at least two qualifications: (1) literate and (2) has a good grasp of Classical poetry.
Classical poetry is a must, in order to know the patterns and requirements for the couplet or quatrain that would be created... things one needs to know include, beyond simple "rhyming," include knowledge of tone categories, grammar/syntax, and similarities/crossovers/homophony of characters.
For clan lineages that do not "recycle" their poem, another added constraint is that there is avoidance of any repetition.
5. How long would it have taken for a scholar or poet to write a new family poem?
Again, because this is a committee effort, timing is indeterminate.
If there is consensus, it might take as short as a day with the guidance/contributions of highly literate committee members.
Even if a committee is comprised of highly literate committee members, the process could take days/weeks/months to come to an agreement over "what's best".
Compounding the delays beyond mere consensus, things like auspiciousness calculations and discussions with collateral lineages might be in order, too.
6. What is involved in writing a family poem?
Too open-ended a question, since that could vary from lineage to lineage.
Poems are usually meant to extol family virtues and exhort generations to come; sometimes collateral lineages' poems will be complementary and complimentary at the same time.
7. If I want to find the family poem for the Cheng family, for instance, what info do I need to provide and to whom?
(1) you have to find out the lineage of the Cheng family in particular... information to help _might_ include as many male names up as much as possible, PLUS knowing the home village;
(2) some families don't remember; some villages also don't remember... doing the genealogy research to find collateral branches of the same lineage would be the next step.
SOME clans, like the Guan/Kwan/Quons and Szetos/Soohoo/Setos in Hoiping have clan libraries that coordinate it all...
Most don't...
8. Much of the discussion I've read about family poems seems to focus on the generation character aspect. Can you please explain the precept aspect?
What do you mean by "precept"?
9. Although it may not be as popular a tradition in modern China to retain or use the family poem to select a baby's name, perhaps in the more provincial villages and areas, the tradition is still strong. Is that possible?
Henry mentioned that there are numerous names a person, especially a male can have.
Birth names in most families (but sometimes in some) will *NOT* use the generation poem, because that is usually reserved for when a male is established. Like
Henry mentions, in the Sìyī region (especially, Toisan/Hoiping/Sunwui (unsure about Yanping)), the name that uses the generation poem is usually given after a male marries.
Selecting baby names is a completely separate process unto itself.
The only overlap is that SOME families will choose a character for people born in the same generation to share—sometimes it will be birth-gender-divided, sometimes it will be shared regardless of birth gender; sometimes characters are chosen randomly, sometimes characters are chosen to be topical for the times, sometimes it will come from a poem like the generation poem (but will not be "official" and may or may not match the "official" generation poem.
10. Was it the case that children were required to memorize their family poems as part of their education? During what period of time may that have been the case?
Home education, yes.
Outside school education, no... if you made it an outside school pre-PRC times and didn't know your family's lineage/poem, you would likely really be considered uneducated...
11. Did every clan once have a family poem?Generation poems didn't really start to be used until the Sòng Dynasty... when lineage management became more important... for some lineages in some regions.
To make such a statement as above would be ... absurdly stretching it.
