doable is a thing , but beside the 3 holiday , one need to do another 3 long haul trip , how many (hk)people is able to pay for 6business class ticket and what industry in hk can have so many day off a year? so , this group of people is really really small amount compare to the moved out big companies that do have a lot of business trip . so i just dont understand how come the DM number would be increased , the maths didnt add up at all.
