Chinese vs. Canadian

It's been over two years since I came to Canada. Compared with 21 years' life experience in China, I think I live in a more comfortable way here. The environment is awesome, less polluted and harmonized. People in Canada are one of the most friendly one all over the world. Love and peace are the theme of the city and the country.
Not until things happened, did I feel that there is something wrong here! It's the young life of Amanda Todd passed that let me be aware of something. I strongly felt the same feeling of being isolated. I realize that the new immigrants or international students in this city are welcomed and also group into a close community. Many Chinese students in SFU as I knew have never deeply got involved in other races' community.
I am such an easygoing and outgoing person who are always looking for friends from other races. I speak English with little accent, but I found the language definitely not the barrier. People even like me can hardly make some real friends here.
I am trying to look for some reasons. First, SFU is a localized university, most of people here are from greater Vancouver or BC province. These people normally stay in Vancouver before they come to SFU. They have their friends from high school. Even make new friends in the university, they are more easily to be merged together. Second, people in the west are educated implicitly or explicitly to avoid to disturb others. Laws are firmly executed and individual rights are demonstrated. People won't ask for help unless they have to. That leads to apathy. You may argue that there are so many fundraising events happen everyday, but, does people really care? Most of time what a helpee needs is attention, love, sincerity from the helper.
Chinese (at least in mainland China) work in the opposite way. Chinese people are so easy to cross the line and offend the others. People are not used to negotiation, compromising, making a promise and keeping the promise. People so naturally trample others' privacy, even though they feel uncomfortable when they are offended. However, people care more about each other in a community. People might not be willing to donate a lot money, but they really care about the helpless, physically or mentally.
I think that may be the sacrifice of a nomocracy society. And for Chinese, the cost is the hurting which happens when conflicts show up.
