I wanted a lora for mianguan hats for quite a while now, as there is only one for sd 1.5 out there. It frustrated me that ai seemingly couldn't draw these no matter what, and it's honestly a huge oversight in my opinion given how much Chinese people use stable diffussion and all they've contributed to its community. That said, unlike a lot of them, I'm no expert in ai or programming, and the data that I had to work with was not the highest quality stuff that you'd train a lora on. Most of the images of mianguan that I could find were horribly low-res, so I was stuck using whatever I could find that was higher in resolution and upscaling a bunch of them, so I don't expect this lora to be perfect. That said, it's still huge progress over SDXL in general, which will at best generally give you a qing emperor hat/western crown hybrid pretty much no matter how you prompt it. It still seems to struggle with actually overlaying the beads over the character's face from what I can tell, so I might come back to it and update it if I can get some happy accidents where it does that correctly to train it on.
It should be able to manage decently in a number of styles, from anime to photo-realistic and a somewhat more traditional chinese illustration style(though I would combine it with additional loras if you want it to get that 100% right) and be able to do males of all ages, women(at least young ones, I haven't tested it on old ladies) and so on and so forth. There's quite a few tags that you can use to point it in different directions, so I'll list them with a brief explanation below.

The trigger words are: mianguan,MG_chinese_emperor,MG_chinese_emperor_hat,MG_bead_hat
Other than that, you can use:
MG_profile_front, MG_frontal, MG_side, MG_profile_back, mg_behind, side view = pretty self-explanatory, the angle.
mg_slim_base, mg_thick_base =the thickness of the hat-part supporting the beads, from more official guan-type minister hats for thick and all the way to more high-ponytail type hair-bun crown-type thingies.
mg_detailed_beads=highly recommended
mg_jewelry_base=more like jewelry, less like a velvet-type hat.
mg_brocade=embellished fabric
mg_tall_hat_base, mg_short_hat_base, mg_medium_hat_base=the height of the hat
mg_Straight, mg_s-curve = nothing inappropriate is going on here actually, this just controls whether the part that the beads hang from is more just like a straight plank-like board or has a curved shape
mg_gilded, mg_gem, mg_pin, mg_filigree=again pretty self-explanatory, adds ornamental and structural elements like gems, hair pins, and gilding.
mg_headdress_Style=especially jewel-like styles
MG_short_hair, mg_long_hair=short or long hair for the wearer
mg_long_beads, mg_short_beads, mg_medium_beads=how far down the beads reach
MG_dangling, MG_still=whether the beads should be static or moving
MG_beads_over_forehead, MG_beads_obscure_face=well, you can probably tell what this was supposed to do, hopefully it'll do it.
mg_attractive, mg_slim, hanfu, mg_beard, moustache, middle-aged, young, old, man, woman,etc=how the wearer will look
mg_doodle=points it more towards an illustration-y art style and less photorealistic.
