I might point out for artist search purposes that the account linked in the commentary seems to be just one with various MutsuSaki public commissions from different artists and commissioners, although I'm not a chinese-speaker so I had to ask other users to be sure about that.
Edit: is the second line about the commissioner account or the artist one? Because another post for the same community day makes me think that it's actually the latter... Also what they mean with "mhs"? Is it an acronym of some other social?

"mhs" is a painting invitation software,the full name in Chinese is“米画师”, and the author's name should be called "second秒" in the software.

I had no idea about what Mihuashi was so now I managed to find the artist profile here, thanks for your help!

...Although minutes later I found that the artist entry was already here, so at least I can safely confirm some other entries from this community day and search up better the rest of them...
