On Friday evening, train No Z113 arrived at Harbin Railway Station in Northeast China's Heilongjiang province, carrying equipment for two N95 facial mask production lines from South China's Guangdong province.

Heilongjiang is facing a shortage of facial masks on the front line of the fight against the novel coronavirus.

To meet the massive demand, Harbin Pharmaceutical Group Holding Co Ltd, better known as Hayao, purchased two N95 facial mask production lines from Dongguan city in Guangdong province under the coordination of the provincial government.

Leaving Dongguan early morning Thursday, the train with the equipment arrived in Harbin 34 hours later.

"One production line has been assembled overnight in our factory," said Sun Jintao, director of equipment management at the company's general factory. "It is expected to start production next Monday, with a daily output of 20,000 to 30,000 N95 masks."

Simultaneously, many domestic companies are transforming their businesses to provide medical necessities like facial masks for workers fighting on the front lines.

The 12 production lines, including four for N95 facial masks and eight for surgical masks, will be put into operation by the end of February after reconstruction in a 2,000-square-meter dust-free workshop in Liuzhou's SGMW, a joint venture between General Motors and Liuzhou Wuling Motors that founded in 2002 in the Guangxi Zhuang autonomous region.

Daily output can reach more than 1.7 million, which will greatly help relieve the shortage of medical supplies in Guangxi and provide support for epidemic prevention and control.

In Fujian, workers of the famous diaper manufacturer Daddy Baby are busying revamping their original production lines for producing masks.
