After the coronavirus outbreak in late January, even though high demand from customers never waned, the company could only run at 70 percent of capacity because of a shortage of staff and the shutdown of supporting downstream businesses, including packaging, logistics and warehousing companies.

To solve the problem, the administrative committee of the Tianjin Port Free Trade Zone, where the company is located, set up a special group to help supporting companies resume work in an orderly manner, and it ensured the payment of subsidies to workers.

Lee is confident that this year's sales target of 3 billion yuan ($430 million) is unchanged. Meanwhile, he suggested, the concept of "staying together in the same boat", which means relying on each other in difficult times, as the first item in the enterprise's development policy this year.

Zhang Lingxiao, deputy director of the free trade zone's administrative committee, said: "We have made specific arrangements for the employees returning to the factory and the company's need for subsidies. Moreover, we have built connections between banks and enterprises to ensure companies can be financed in a timely manner."
