Chinese money behaviour

It seems that Chinese people like cash... First of all it's not easy to pay with card everywhere, mostly only at a little more posh stores and restaurants. It's not like in Sweden when you can buy a chewing gum with card. This guy on the picture have the whole bag full of cash. (It's a bad picture but I had to sneak to take it) Mostly hundred RMB bills in big packets of several hundred thousands (maybe 10-13 cm thick). Shit, I would not even dare to carry that much money out on the streets. While they where cashing in the money to a bank account (took more then 15 min, then I left) another guy took out money form the bank; one of these big pile of hundred bills that he put in a modest cotton bag.
