On Thursday at one spacecraft, three Chinese astronauts left a system module bound for Earth to finish the third of more than 10 missions needed to finish China's first space station by the end of the next year.
The astronauts left Shenzhou 12-first module on the Tianhe probe after spending 90 days in space, a record for China, according to state media.
Construction of the space station began with the launch of Tianhe, a small module slightly bigger than a City Bus in April.
The module is finally the living quarter of the completed station.
Four out of 11 missions to accomplish the station being built will be crewed.
The next crewed mission will last for six months.
Prior to that China will send another automated cargo spacecraft - the Tianzhou - 3 - to Tianhe carrying supplies needed by the next crew.
Tianzhou - 3 spacecraft will be launched in the near future, state media said recently.
