During the Sui and Tang Dynasties, the unity of ancient China and the prosperity of economy brought about new thoughts, and the dress became very good. Because of the intensity of the feudal ideology, the patterns of dress and adornment gradually became conservative from the Song and Ming Dynasties.

All you have to do is type your name into NASA’s “Adopt the Planet” site to claim a certificate that will give you the location of your slice of paradise (天堂) complete with details of its environment. NASA hopes that this exercise will stimulate interest and care in our planet.

Search giant Google is also trying to engage the public with an updated Google Earth focused around Earth Day events. Through a new Voyager feature, users will be able to discover stories from around the world, learn about new places by reading “Knowledge Cards” and send postcards.

If you happen to be anywhere near the nation’s capital on April 22, join the millions that are expected to participate in the Earth Day March at the National Mall.
