It was Sunday yesterday. Wang Jun and Li Qiang didn't go to school. They went to the museum. They saw many photos of planets (行星) there. The photos were very interesting. They also saw photos of an astronaut (宇航员). He was the first man on the moon. His name was Armstrong and he was from America.
Wang Jun and Li Qiang wanted to know something about Chinese space industry (航天工业). So they watched a video about the Shenzhou spaceship. And they knew Shenzhou IX sent three people into space in 2012. They were very proud of our country.
