BEIJING — China's transport system is expected to see millions of migrant workers finish their return to their workplaces in early April after a prolonged Spring Festival break due to the novel coronavirus outbreak, an official said on March 7.

The country's transport authorities have introduced tailored services to facilitate their safe return, said Cai Tuanjie, an official with the Ministry of Transport.

The latest official data showed that 78 million migrant workers have already returned to their jobs. In the provinces of Guangdong and Zhejiang, 70 percent of migrant workers from other provinces had made it back to their workplaces.

A total of 27 provincial-level regions have arranged about 80,000 "point-to-point" customized buses, sending 1.7 million migrant workers back to their employers directly.

Measures such as online ticket selling and coordinated transportation will be taken to reduce the health risks in migrant workers' return journeys, he said.
