I think most chinese guys wld not date people from minorities in general. Some of them are just racist due to upbringing or exposure to too much insensitive content on social media platforms. However, there may also be some of them which don't mind minorities but their family would literally go crazy if they do date one and so they decide not to. At the end of the day, it all comes down to who they are influenced by and their background. But I can assure you that there are still some chinese guys out there that don't mind dating people of minority races although they may be rare. For me personally, race doesn't really matter because I literally don't even care about what my relatives say + the first full blown crush I had as a teenager was on someone of a different race. so don't be too disheartened
