A birth, a death, a pilgrimage. A film about the 1,200-mile journey of a pregnant woman, a butcher who wants to atone for his sins and a rag-tag band of villagers who go on foot from their small village in Tibet to the sacred Mt. Kailash has become a surprise winner at the Chinese box office. It has also found a cult following among an unexpected audience — China’s venture capitalists and startup founders.
