Genowise, a gene testing product and service supplier in DLSEIZ, has sold 250,000 saliva collection kits it independently developed since the products were put into market last year.

"The customers can collect their saliva with the kits at home, send them to the testing center by express and check the results on line," the company's general manager Jiang Junfeng was giving an introduction to the product.

Jiang joined the company in 2014 as a department head. Now he is the general manager, the winner of a long list of honors from provincial and city governments as well as an active promoter for initiatives devised to give youths a helping hand in their self-development and business operation.
