China's Shenzhou-21 and Shenzhou-23 astronaut crews held a handover ceremony on Thursday, during which the Shenzhou-21 crew transferred the key of the country's space station to the latter and conveyed their best wishes.

The Shenzhou-21 crew has now completed all planned tasks. The three astronauts will take the Shenzhou-22 spacecraft and return to the Dongfeng landing site in north China's Inner Mongolia Autonomous Region in the coming few days, according to the China Manned Space Agency.
