In the bustling Yantan Small Commodities Wholesale Market in Lanzhou, Gansu province, Wang Cheng stands out among vendors selling plastic basins and cooking pots. The 31-year-old, wearing a plaid shirt with faded cuffs, recently gained online fame for filming product videos in fluent English with a striking American accent on Douyin. His videos promote stainless steel stockpots and other kitchenware, creating an unexpected contrast between his polished English and the ordinary shop setting.
