We watch extended sentences in the Tiangong class.

1. Following the astronauts, we visited the candlestick experimental cabin and saw the whole picture of China Space Station. I can't help but sigh the strong development of national science and technology, and I am also impressed by the creative design of China scientists. 2. Through this "Tianguan Classroom" study, I feel that China astronauts are climbing and challenging the unknown. Their perseverance of "sharpening a sword in ten years" has aroused our enthusiasm for loving, advocating, studying and studying science, and played an inestimable role in cultivating scientific talents for the motherland.
