Su Hua, the co-founder of short video app Kuaishou, stepped down as chief executive officer on Friday but remained chairman of the board. Kuaishou’s other founder Cheng Yixiao assumed the chief executive position. Su joins a list of Chinese tech executives to take a back seat in the daily operations of their companies amid a regulatory shake-up of the sector. Su’s stepdown follows similar moves made by Pinduoduo founder Colin Huang and ByteDance founder Zhang Yiming earlier this year. [Reuters]
