You and your family will just love China - it's a really wholesome kind of place.
The people of that nation are highly cultured, polite, approachable and most of all hygienic.
The air quality has improved in leaps and bounds over the last few decades. I would say it rivals that of southern Africa now.
But most of all, Spring Airlines, or any other excellent airline in China will treat you with respect, and as an equal.
Enjoy the experience
