The first "Tiangong Class" will begin at 3:40 pm (Beijing Time), December 9, given by the three Shenzhou-13 crew members aboard China Space Station, Zhai Zhigang, Wang Yaping and Ye Guangfu. The China Media Group will live stream the whole event.

The astronauts will interact with students on the Earth during the activity from space. The primary ground classroom will be at the China Science and Technology Museum. Classrooms will also be set up in Nanning of Guangxi, Wenchuan County of Sichuan, Hong Kong and Macao. The astronauts will introduce and display their living and working scenes in China Space Station. They will also demonstrate cytological experiments, the motion of objects and the surface tension of liquids in microgravity environment (teaching items attached). They will have real-time interaction with the classrooms on the Earth to spread the knowledge of manned spaceflight and inspire young people.

Chinese astronauts sincerely invite young people to carry out relevant experiments simultaneously to feel the mystery of the universe from the difference between space and earth and experience the fun of exploration.
