Photo taken on September 6, 2013 shows a rubber duck wearing a green vest and followed by seven green eggs at Yuyuantan Park in Beijing. Since Dutch artist Florentijn Hofman's giant rubber duck became a sensation at Hong Kong's Victoria Harbor, a wave of ducks has swamped the country with various copies. Now Hofman's rubber duck is exhibited at Beijing Garden Expo Park. (CNS/Wen Chenjian)
