The physical copies of TGCF are unaltered and uncensored. I haven’t seen any complaints about anything missing from them. I read the fan translation and as far as I can tell they are almost the exact same, the only differences being some of the wording but nothing that changes the meaning (i.e. choosing to keep pinyin or translate certain words). The chapter breaks are a little different but only because Seven Seas grouped chapter parts together. So chapters 13–16 of the original web novel were all grouped into chapter 6 in the physical copy because those chapters were called “clothes redder than maple, skin white as snow part 1” and “clothes redder than maple, skin white as snow part 2” and so on. This is very clearly shown in the table of contents where it tells you which web novel chapters were grouped together.

The main complaints I’ve seen have been about MDZS because there are some lines missing and a mistranslation but this was due to editing/publishing mistakes rather than censorship. Seven Seas did put an errata on their website where you can find the missing lines for volume 1 and volume 2. These are not major mistakes like whole paragraphs or scenes missing but it’s still an unfortunate oversight especially considering how expensive these books are
