Fei Xiang runs his coffee roaster in a food truck, selling coffee, pastries and desserts just like other similar outlets. He, however, decided to add the free “game of the day” offer to his menu. /Chinanews Photo

He said he wanted to improve the community’s environment. /Chinanews Photo

Fei said he could offer five to ten free coffees on average every day. /Chinanews Photo
