In November 2021, in order to greatly improve nucleic acid testing capacity in a short time, the "Di’anleidi" hard air membrane laboratory with two groups and three cabins in one began to be built in the night of November 12, and was officially put into use on November 13. It injected an important force into Shangrao city in Jiangxi Province to control the spread of the epidemic.

On December 12, 2021, under the emergency deployment of Zhejiang Provincial Health Commission, a set of "Falcon" hard air membrane laboratory with five cabins in one rushed to Shaoxing. It arrived at Shaoxing Olympic Sports Center in less than 6 hours, completed the construction of air membrane and pre-experiment work in 16 hours, and officially put into use at 2 am on December 13. It began to undertake large-scale nucleic acid test samples from Shangyu District and Yuecheng District of Shaoxing City, and became the earliest and fastest air membrane laboratory engaged in the "battle" in this round of epidemic prevention in Zhejiang Province.

In the face of the epidemic, Sijia bravely took social responsibility, used Sijia membrane materials to help our country to build nucleic acid testing laboratory and to contribute to the fight against the epidemic!
