Re blogging for additional resources

so I know that a lot of chinese names are references to specific poems. Is there a way to determine this (vs general auspicious meaning) and which poem specifically? I'd love to be able to figure this out for character names and I haven't been able to find any resources (in case it's helpful, I'd say I'm my understanding is maybe HSK4-level so I can clumsily make my way through the chinese internet with the help of a dictionary)
feel free to make this public so that others can benefit if you have any suggestions
oof... unfortunately I suspect that this, along with one's repertoire of chengyu, is something that one simply Just Learns with reading more. my personal repertoire of poetry is embarrassingly thin, so the horrible horrible process I've been going through is, well, throwing the name into a search bar and hoping for the best.
here's an example of how I (think I) went about doing this for Xiao Xingchen's name, way back when I wrote this post:
I went ahead and dropped "星尘 诗词" ("Xingchen poetry") into the search bar, which turned up this:

Generally speaking, I'll only put the name (minus the surname) because putting the character's full name into a search bar will probably turn up the character themselves, and if someone's name is being derived from a poem, it's usually independent of the surname anyway.
Xiao Xingchen's name is an interesting example because it doesn't quite come from a poem, but it doesn't not come from a poem. you can see that the search engine has automatically assumed that I am looking for poems about constellations, as "星辰" and "星尘" are homonyms, and one of these is more commonly seen. I usually consider that a solid indication that "星尘" (the name) is a novel formation of characters in a name, and not likely a poetic reference.
but! in for a penny, etc. I'm a huge fan of the first search result, gushicimingju, since it's a solid database of poetry and some prose. clicking into that listing informs me that gushicimingju is turning up. oh my. 119 possible matches:

note that these are matches for "星辰" (constellation), not actually our character's name. still! you can click in and peruse the selection if you'd like.
now that you're on gushicimingju's site, you can also use the search function within the site to search for more exact matches, without worrying that you'll accidentally activate the fandom itself.
looks like there's a few matches for "晓星," but nothing for the full name.

so! gushicimingju is a solid database I like to refer to most of the time. if for some reason I'm feeling particularly academically rigorous, I might also do some searches on ctext as sometimes names will come out of famous turns of phrases (a la Zhao Yun 赵云 / Zhao Zilong 赵子龙 from that post I linked earlier) rather than poems. searching the dictionary sometimes (Pleco, or zdic) doesn't hurt either. basically, I throw spaghetti at the search engine wall to see what results come back for these characters in this particular order to try and get the original referent (if any) to show up; I'll probably give up after a few permutations of search terms if nothing is actively jumping out at me
but back to the search results: sometimes, if your character is famous enough, straight up searching for "what poem is this character's name from?" will help you find like-minded people on baidu zhidao (basically yahoo answers):

although of course, take baidu zhidao result with all of the salt you would take with any yahoo answers (look for alternate sources to validate, good for a laugh most of the time)
best of luck!
