Since January 2020, the outbreak of the COVID-19 virus has severely affected China's manufacturing industry. After nearly two months of national isolation, Wenzhou Langrun Electric Co., Ltd. officially resumed work and resumed production on February 24, 2020. In response to this resumption of work, the company actively assisted non-local registered employees to handle rework. Corresponding plans for prevention and control were formulated. When employees enter the factory area and undergo strict sterilization, each employee must undergo strict body temperature detection every day, and their body temperature is sampled from time to time using instruments. As of March 10, 2020, our output has recovered to 80% at the end of 2019.
