The World Harmonious relation

I grew up in the countryside in India. Of course there was some advantage of getting fresh air, enough place to play, and a healthy social life which i realised since started living in urban areas. Moving from a rural place to towns, cities, metro cities, metropolitans, and now in a cosmopolitan, i constantly borrowed the values of that place except thought, idea, opinion which changes over time. And it is just because, i came in contact of those i used to express a negative opinion about. Now again i realise something new and it is uniqueness in harmonious gesture in the people around the world.
Presently, i am at the place (Hong Kong, an independent territory of China) which is not being considered in the good book of friendship with India. We have had dispute over several issues, mainly line-of-control and thatswhy we had even in the battle in 1962. When i planned to move here my family, relatives and friends were started crying on me. They tried to draw my attention on some notorious activities restated by Chinese troop in J&K and Asam. Even i was a bit scared of starting this journey but came forward with a mindset to handle all challenge in the way.
Once my flight landed at HK airport.....i found everything friendly. The life was fast, modern, automated but still co-operative. People were responding same like my places. And something even are more effective on ground like; rule-regulation, honesty, and respect to senior citizen. Unlike our places, here government employee work fast, response quickly and behave friendly. It is hard to predict that the university staff use to make a call when something getting late or wrong. It is not once but may be more until they fully convince oooooo...now it is ok. Just few months in HK changed my opinion toward the people republic of china. Except the minor facial difference and that only due to geometrical changes, everybody looks like same, do same things, eat same food, and almost similar culture.
Imagine, they have same way of expressing the things as of ours.... joy, sadness, ritual, rhythm..... . A psychological research said that most of the facial expressions have same emotion in all people. It is above the political and geometrical line. So far, I have not been treated badly by anyone and even i get more love and preference than local guys in department. ...................everything is fine....then what is wrong b/w us? Why we have had a negative thought for these people? Should we judge a person, place, & thing just on speculation? Absolutely not......i think this is only a reason why our relation is being deteriorated day to day................................The world has similar harmonious gesture to express; love, emotion, and feelings and it gives the inner beauty to human then why we should be differentiated on geometrical ground.
