A sanitation man walks into a noodle shop in Lanzhou, capital of Northwest China's Gansu province.
It's-8 C outside, so he orders a traditional breakfast bowl of beef noodles to warm himself up.
Lacking the money to pay for the dish, the man simply points to one of the heart-shaped tokens pinned to the wall behind the counter.
