How an ancient Chinese military dish became a social media darling

CHONGQING, China -- Nestled in the mountains of China's inland Chongqing municipality, Fuling district is busy marketing itself as the birthplace of a pickled mustard tuber famed for its crisp and savory flavor.

And thanks to livestream sales events that hawk fruit-flavored zhacai to young Chinese, the humble pickle that history links to the legendary military strategist Zhuge Liang from the Three Kingdoms period (A.D. 220-280) is enjoying something of a renaissance.
