A paddy field emblazoned with the Shanghai World Expo logo is seen at a town in Pudong district, Shanghai on August 4, 2010. The rice logo, 27-meter long and 20-meter wide, is produced by Minhang Agricultural Cooperative and Shanghai Chuangbo Ecological Engineering as a gift to mark the 100th day since the Expo's opening. Planted more than one month ago, green rice is used for the grounding color, yellow for outline of the logo and purple for the character. [Photo/Xinhua]
