Milky Way is thriving despite Shanghai's closure.

The leading chemical supply chain service provider has four outlets in Laogang Town, Pudong New Area, where a district-wide lockdown was announced on March 28. However, they continued to operate normally, with the industrial park extending its nucleic acid testing services to their doorstep.

The company said that despite the lockdown, the four outlets reported a joint revenue of 520 million yuan in April, up 51 percent year on year. First-quarter revenues rose 70 percent to 2.15 billion yuan.
