Fascinating patterns were formed in the sky over Rencai Park on the evening of August 26 to celebrate the 40th anniversary of the establishment of the Shenzhen Special Economic Zone. Glowing patterns like Shenzhen's iconic buildings and logos reading "Time is money," and "Efficiency is life" appeared in the sky. The 10-minute performance near Shenzhen Bay attracted thousands of citizens to take photos or videos from the nearby bridge. Some came to the bridge with cameras and tripods several hours before the performance in order to get a good spot.(Photos: Li Hao/GT)
