'Snack' packages help seniors pay power bills

A product that allows buyers to pay electricity fees for seniors living in China's remote areas has sold very well among residents of Nanjing, Jiangsu province.

The package, which resembles a snack and is sold at 10 Lawson convenience stores in Nanjing, has photos and brief introductions of the seniors. It also has a QR code for the buyers to pay the fees.

They will pay at least 2 to 3 yuan ($0.29 to $0.43) toward the seniors' bills when they scan the code. Each package, with no real food inside, contains a piece of paper with a message.
