Deng set himself the business goal of promoting Lanzhou's beef noodles to the whole nation, and allowing more people to taste the genuine article without having to travel to Lanzhou.

In September 2013 he and two other masters graduates all quit their jobs and started to focus on the online beef noodle business.

In order to guarantee the quality of the soup and the chili oil, which are the two most important ingredients in genine Lanzhou beef noodles, Deng and his team sought out a master cook who had 30 years of experience in making Lanzhou noodles, and visited his home several times to learn his secrets.
