The problem here is that Hong Kong people are brought up to be introvert and often inward looking. In some situations, they put themselves in disadvantage by not communicating with people who are outside their own environment and comfort zone and they suffer from info blackout. I had quite a few experiences in the past at various international airports and cities, trying to help Hong Kong people on some local issues when it was apparent that they were not getting the right info and doing the wrong thing but they just walked off everytime when I went forward trying to talk to them. I met some BNO people in the UK too in the past year or so and many are still like that but the smarter ones like these 2 are opening up more, making effort to communicate with other people which ultimately only benefits no one else but themselves. The western culture is very different as people go to parties and social functions at very young age and you get used to the idea of introducing yourself to strangers and talking to practically everyone in the room and outside the room! Hong Kong people, especially men from their mid 30s onwards and the women in their 20s/30s, they seem to get tongue tied with zero social skill which is not going to help them to get job offer!
