Ms. Zhou, the founder of Lens Technology, owns a $27 million estate in Hong Kong. She jets off to Silicon Valley and Seoul, South Korea, to court executives at Apple and Samsung, her two biggest customers. She has played host to President Xi Jinping of China, when he visited her company’s headquarters.
Ms. Zhou has honed her hands-on knowledge into a world-class, multibillion-dollar operation, one at the vanguard of China’s push into high-end manufacturing. Lens Technology is now one of the leading suppliers of the so-called cover glass used in laptops, tablets and mobile devices, including the Apple iPhone and the Samsung Galaxy. This year, her factories are expected to churn out more than a billion glass screens, each refined to a fraction of a millimeter.
