You got it right that moving to the West would only geominn, and I do not like living in Japan(I am not being overpatriotic. I just don't fall for Japan).
It's normal, I can understand it. I also don't like living in Japan, even when I do love the Japanese culture, including food, enka songs, many of the Japanese inventions and a big part of the Japanese females.
It's just not my place because of its regular earthquakes, cold winters and the fact that almost all of the Japanese neighbors are hostile or not very friendly to Japan (the Koreas, Russia, China. Only with Taiwan they can make some better relationship as far as I am informed.)
The requirement for height is elevating generation by generation, and by 00s, the cohort which I belong to, the girls are filtering out the boys under 175 or even 180cm!(which for sure is kinda dumb since imo if a man is taller than 170cm in China, he is just normal. I hope one day the gaslighting in China that a man must be 180cm or he is not a man can be terminated)
Depends on the area. For example, around me where the girls are around 1.55 m to 1.65 m, even the males who are 1.60 m can date. I see some tall but fat boys without girlfriends. Looks like being fat is an issue more than being short around. Just fatcels are more filtrated that the shortcels which are not real shortcels when most of the local females are shorter too.
"he is not a man can be terminated" -- this is more like some Western girls. It's not a very popular attitude in China. To be honest, the only ones what "can be terminated" here (according to Chinese people, but not every Chinese) are the Japanese. Of course, after the new trend, maybe later the xenophobia will spread more towards other foreigners, especially the USA's as I see but currently it's rear to hear something like "The shorties must be terminated."
Tbh to me is it unfair, because I never humiliated midget-tier, fat, ugly girls, but I gotta be humiliated.
Like how? If they point to your flaws or something? Because I also got maybe more than 200 rejections but usually they're like "你烦不烦?", “我有男朋友。”,“我喜欢女孩子们。你相信吗?”,“删吧。”,“你多大啊?!,“我不喜欢外国人。” ("Are you annoying?", "I have a bf.", "I like girls, can you receive it?", "Deleting, okay.", "How old are you?!", "I don't like foreigners.") which aren't so polite and aren't what i wanted to hear but I can't call them humiliations. How about you?
Often the situations in the life are "or-or". You can't have everything anytime. If you want better education + height mogging, this is the USA. If you want worse education + height geomaxx, this is in the Southern regions (like South Asia and South East Asia, South America, etc.) If you can deal with being short (even more short than now, because it's relative), there will be no problem to be in the USA or Sweden, Norway, etc. And just don't forget to improve your other aspects. For example, healthmaxx, don't healthminn because most of the women never agree to marry an ill person. For them an ill man is like a disabledcel.
