In the vast universe, there is a blue spherical celestial body, which is the home of human survival and development. The earth is a unique member of the solar system family. It is the only planet with life development and human activities in the solar system. It is also the only celestial body with biological evolution and highly civilized development in the universe.

On the earth, the land covers less than one third of the area, but it has complex and changeable landscapes: endless plains and rolling hills; dense forests and vast grasslands; water towns in the south of the Yangtze River with small bridges and flowing water; the desert in the western regions where people are rarely visited; the beautiful scenery of the equatorial tropics, and the snow wrapped in the north and south poles; the Himalayas piercing the blue sky There are also breathtaking Colorado Grand Canyon.
