Maybe I am living in another society that I really don't understand what you are saying. If I am noot wrong, you said that you think someone have some special realtionship with big people and therefore you can't join the exchange program to HK, isn't it?
Actually, HKIE...... most of the top students now in HK would not choose to study in this school. Therefore, don't be so sad for losing this chance!
Now in HK, many schools are holding exchange programme with China( just to show that they are preparing their students know much about the mainland). Hence I am sure that you can have a lot of chance in the future. Maybe next time, you can apply for HKU or CUHK, but the others cannot!
I will pray for all the students here.
