Around two decades ago, Wang Chuanfu created and followed through with a plan of buying a government-owned car manufacturer that was failing so that he could start manufacturing electric vehicles. This company, BYD, is now so successful that its sales of battery-powered cars rivals Tesla. When the COVID-19 pandemic began, Chuanfu was among the first people in the business world who pivoted their businesses to meet the demand for masks—at one point producing around 5 million of them every day.
