Three Chinese astronauts who successfully completed a space journey on Sunday came back to Beijing on Monday morning.

The China Central Television (CCTV) reported that the astronauts, Zhai Zhigang, Liu Boming and Jing Haipeng, are in good conditions.

After completing China's first human extravehicular activities in space and a few scientific experiments, the team landed Sunday afternoon in north China's Inner Mongolia.

After arriving at the space program headquarters in Beijing's north suburbs, or the space town, the trio spacemen separately rode on three roofless sedans in a miniature parade.

They are expected to undergo two-week preventive quarantine in the medical facilities in the space town.

Although they have passed brief physical checkup soon after their perfect landing, the astronauts are still vulnerable to viruses on the Earth, says medical experts.

Meanwhile, medical experts are going to thoroughly check their physical and mental health.

Since 2003, China has sent a total of six astronauts into space, including the country's first spaceman Yang Liwei, who is now a major general responsible for astronauts' training, and the first pair Fei Junlong and Nie Haisheng.
