Altough this wil be annoying since we all know how much china hate japan and how brainless and unreasonable they are by nature, to this Add the fact the first quirk user was born in china now their endless unjustified ego blown up. Also im sure they are not happy with almight being known as the strongest hero, since for the plot we know the only hero in the world able to match him is Star and Stripes from EE UU sighhh meaning they will be bothering japan and by extention MC, very funny how chinese mcs hate japan and call them everything but they dont care to add japanise waifus in their harem.
