I'm Asian, and was born there as a baby, the air isn't the best there unfortunately. I get bronchitis too easily, and at times, when dust gets into my lungs, I start to cough. When I was a kid, it was hard at times, and for about a month, I started having breathing problems (Bronchitis.), but I got better, so, I really don't know? I've never been tested, just have been sick a lot, if there are any doctors out there who could answer this, it would be great. Thanks for reading this!

What part of Asia? I'd say you do have asthma there are several catagorys of asthma I have active induced asthma. I would get tested if I where you you never know if you could need an inhaler

It is possible, but hard to say, you have enough signs to be tested

China. I shouldn't say excatly, but in the middle, North of Hong Kong.
