Lanzhou beef noodles lovers pay it forward to the needed

Colorful Post-it notes with best wishes cover the walls in a beef noodles restaurant in Lanzhou, capital of Gansu province, northwest China. Each note represents a combo meal, pre-paid by customers who donated 10-20 yuan. Anyone who cannot afford a meal can enter the restaurant and exchange a Post-it note for a bowl of beef noodles, one bowl at a time.
