Tiens Group sells mostly health and household products to consumers in 190 countries, the company told the New York Times. The company has made its founder, Li Jinyuan, exceedingly wealthy: He was worth $5.8 billion in 2013, according to the Hurun List.

But Tiens products have been accused of being exploitative and ineffective. An unnamed employee told the New York Times that the products are sold by sales representatives who are paid on commission, but earn no base salary. As such, a Chinese blogger named Tao Duanfang pointed out (link in Chinese) that the free vacation looked suspiciously like a ploy to attract more sales reps.

“The tactics of direct sales companies are no secret,” Tao wrote. “Above all, they want to create a footprint, because without a footprint they have no endlessly growing source of employees.” Quartz has reached out to Tiens Group for comment and will update this post if the company responds.
