By Saturday, all the masks had been delivered to Central China's Hubei province, the epicenter of the outbreak.

On Sunday, Changchun Culture International Travel Agency sent 3,200 surgical masks collected in Thailand to the local government for medical workers fighting against the epidemic.

The workers of the agency are continuing to collect masks in various ways overseas, and tens of thousands of masks have been donated to Hubei and the local prevention authorities.

"It is our responsibility to support good service related to tourism," said Cui Yuanyu, general manager of Changchun Culture International Travel Agency. "Those fighting on the front line are truly heroes, and we are only doing some negligible work to try to keep them safe."
