BEIJING — Several years ago, Ruby Yang, an Academy Award-winning documentary filmmaker based in Hong Kong, began working with Siemens, the German engineering company, on a corporate video about sustainable development.
She and the company’s representatives decided to try to find a social enterprise in China’s far west, which encompasses the vast Tibetan plateau. Ms. Yang said the company allowed her creative control, with the only major requirement being that the film illustrate how electricity was helping the region, where Siemens had been working with electricity companies.
