LOL! That's because we have had airports for over 100 years (we have over 5000...15,000 when including private airports). In fact we introduced the bicycle to China AFTER we already had airports AND cars!!
Since nobody wanted to use bicycles here anymore we marketed it to you guys. You were very easily impressed with that amazing tech and biked around by in the millions...meanwhile we were snickering about seeing pictures of you guys proudly showing them off while we were driving cars in the millions and flying in planes.
Call us when you hit the 5000 mark...
oh and call us when that new infrastructure of yours delivers drinkable water out of the tap...just something else we have had for over 100 years...apparently you haven’t figured out how to do it yet. Of course when you finally do you’ll be saying our infrastructure is old.
