Pros and Cons of being Chinese!
No need here to list the many wonders of the modern smartphones.
Some people even make a living with their phones by selling stuff.
The stuff is paid using some app, then that app can be used to buy some other stuff (possibly a new smartphone).
The circle is complete.
Friends (that are never met in person), books, movies, business, money, love, entertainment, you name it; you can have everything in that f*****g smartphone.
(Not a Chinese invention, tho.)
