1 hans dont want to live in tibet doesnt mean we dont need tibet....even han soldiers dont want to go to tibet but they have their duties so they r sent to there...and u dont even know this? so does a hindu soldier goes to kashimir mean he will try to convert some muslims there to hindu??
2 hans look slightly different from area to area...mainly becoz weather conditions....what they eat etc etc.......so some may be taller than some others or skin may look brighter........but thats normal.......which can surely be obversed in other races.....how ever there r major differences between hans and some other races in china including tibetan by looking....u dont even look like han how do u becmoe 1?
3 tibet became part of china way early than the day u invaded kashmir.....learn some history my indian friend....
