China has 1.5 billion people. It is very easy to find 20-30 tall women to play voley ball. That has nothing to do with the average person nor it should cause any insecurity to him.
And also, sports like volley need tall players so it is normal the height to ve so important.
For other sports like lifting weights height is a disadvantage. Have you seen anyone to mention the small height of weightlifters in a negative way?
I can understand your point but we should not feel insecure about anything that has to do with height.
My only problem in height is on dating. Nothing else. If someone made fun of my previous shirt height (very rare) I made fun of his tall height or his lack of muscles or something else. Anyone has drawbacks and it is up to us to confront them if they say anything bad about our height.
But women's preferences is something that can't change and thats why I still have problem with my height. Anything else is very insignificant for me, not now I am average but even before LL.
It's not easy to find 6-7 woman, everywhere. Even in a country like China. I remember that the tallest french woman is under 6-7, I know France is not China but it's still a big country of 66 000 000. And I take volleyball as exemple, but that's also the case for beach volley, natation, basketball, handball, tennis, water-polo, etc.
But the fact is that I'm not taking these listening seriously. I really think they are cheated. How can female players be taller than european male basketball player (if we make average on many european team we would find the same) ?
The fact is in our actual world the tallest you are the better it is. I will start to think that Brahim Takioullah is the ideal male.
Hopefully there is some sports where height is not so important. Baseball for exemple, even if there is tall guys there is not that height ideology like in tennis.
I feel that medias and everything around it (so sports) are making everything to belittle simple/average people (and here I'm not talking only about height, but also intelligence, beauty, success). Life was probably better before all of this (before that evolution of informations with TV, radio, internet, magazines, etc). When model wasn't judged (only) on their height and weight but on their general elegance for exemple. We know that there is very tall man, but I don't think that we need to see them everyday at television (NBA, but also some shows).
I really don't understand success of basketball. I admit there is some seductive personnalities : Charles Barkley, MJ, Kobe Bryant, James Harden, etc but that's the only thing good in basketball.
And just a small comparison with Chinese team where average is about 6-2/3
https://en.wikipedia.org/wiki/Japan_women%27s_national_volleyball_teamJapanese team, here the tallest female player is "only" 6-2. And genetically they are similar. So it's clearly a chinese choice to select tallest players or maybe only to upgrade their height by cheating.
