Hey Hong Xing. Good wind up, not too busy are we? I suggest you spend a bit more time in the books - English I hasten to add -that might improve your professional knowledge. I just wasted a few minutes investigating those ten non-english language forums to find that around 95% of the posts are in that dreaded language English. Given the teensy number of ethnic Chinese aviators in Hong Kong, all of whom speak - or should - good english do you really expect the moderators to employ a Chinese linguist to keep posts under a modicum of control?
