Construction workers are busy day and night building prefabricated houses in Gansu so that residents impacted by a recent 6.2-magnitude earthquake can move from tents to warmer structures for the winter.

According to the local housing and urban-rural development bureau, 15,000 such houses are scheduled to be completed by the end of this month in the quake-hit areas.
