HONG KONG - Three Chinese astronauts talked with Hong Kong youth representatives from space on Friday afternoon.

In a real-time video chat, the astronauts in the Tiangong space station answered questions from the youngsters and showed them how to conduct experiments, do exercise and drink water in a weightless environment. Nearly 300 researchers, teachers and students participated in the event co-hosted by the Liaison Office of the Central People’s Government in the Hong Kong Special Administrative Region, the HKSAR government and the China Manned Space Agency.
