"I saw what a friend had shared on WeChat," the 30-year-old said. "The drawing was pretty and I clicked it to see more." She bought the painting for 2 yuan.

"The artist, Xiaolong, is 28-about my age- and has cerebral palsy. When I saw the painting, the orange and blue color pleased me," she said.

Peng said it is convenient to participate in charity giving online. Her last donation went to a project aimed at helping children from rural areas go to school.
