Hong Kong artist Terence Tsang, 28, and his Hunan girlfriend Peng Yi, 24, add finishing touches to their graffiti in F518 Idea Land in Bao'an District on Saturday. More than 100 artists from China, the United States and Germany painted graffiti on a 350-meter-long and 2.5-meter-high wall in F518 Idea Land that day. Organizers said the graffiti wall was the largest of its kind in the city. F518 Idea Land has been listed as a subvenue of the 4th China (Shenzhen) International Cultural Industry Fair this year.
