Zhang Yue, founder and chairman of Broad Sustainable Building, is not a particularly humble man. A humble man would not have erected, on his firm’s corporate campus in the Chinese province of Hunan, a classical palace and a 40m replica of an Egyptian pyramid. A humble man, for that matter, would not have redirected Broad from its core business—manufacturing industrial air-conditioning units—to invent a new method of building skyscrapers. And a humble man certainly wouldn’t be putting up those skyscrapers at a pace never achieved in history.
