Do you relate to your favorite character(s)?
Wang Yao - nooot really? If anything I like him because we're opposites lol, I'm kind of a whiny baby and I honestly respect + look up to Yaoyao in that sense, in his self-control and internal strength to move forward no matter what.
What's a headcanon you need to work out?
Ough this is hard... way before I started fixating more on Asia only, I was actually mainly a UK + China blog, and most things from then I never properly worked out, but this one I always think I'll come back to:
So basically Hetalia is set (in canon) in WW1 and then WW2, WW1 meaning Bad Times for China is well established in the comics but since China's kind of a sidelined character, his real relations with the allies in WW2 is never explored. Now, as countries, the other countries recognized China as the fourth major allied power, however, what this obfuscates is that China joined the war in 1941, but the most extreme and direct economic imperialism and control in China spiked in the 1930s and much of the concessions and colonies held by the other allies would not be returned to China until 1943 - or 1997, in Hong Kong's case. British and American extraterritorial rights would not end until 1943, and a few colonies/concessions that were occupied by Japan over the war were handed back to the colonizers after the war was over. Up until the 1930s, the British were making military excursions into China in order to put down revolts and unrest in semi-occupied places like Shanghai and continue their supremacy there. China is the only major power in the war that was both still semi-colonized and not at all industrialized (it didn't start industrializing until the 1950s, which didn't show much fruit until the 1970s, and was one of the poorest countries in Asia in the mid 1900s)
Basically, I can't imagine he would just be able to joke around with the allies like in canon. Countries are one thing, but just yesterday he was totally destroyed by them and at their mercy, they were prying pieces off of him a couple of years ago and controlling his economy, and now he's their bestie and close allied power? I think at that point the resentment would still be going strong, but also the shame and all that. I don't know how he would act with them, it's really a bare-bones headcanon, but I just think it'd be different from canon. I don't want to like inject racism into canon or something JKDSLGHF but I also don't think they'd be able to treat him normally either, you don't go from racism and colonial/imperialist control over someone you drugged into submission and then used for a century directly into treating them normally and working with them as an equal. I'd like to see the tension portrayed at some point, but Idk if I'll return to this and flesh it out - maybe!
