why?

This is where i am now. I am in China, i've been working as a planner in a multinational firm for a year now. So far, i am enjoying every minute of it. I've been in and out of Hong Kong and Abu Dhabi for the past 12 months because of work...it is physically tiring - ferry, bus, train, plane, you name it - but i am fine with it.
So, why did i work in China? I've been asked and i have been asking myself why...up to now, the only reason i can think of is...because it's China.
Maybe in the next couple of months i will be able to answer that.
But now...i am still enjoying everything...
