to 天涯何處無芳草: u never go out in usa ,that is why

u feel safer here than in china. in fact , most chinese stay at home after work in usa. try go to downtown area of any major us cities at nite, i bet u will agree with me. i was in Miami\'s south beach, i could not leave tourists\' area. even on the beach , i was approached by drug dealers during the day.
