Lanzhou is famous for its beef noodles. But what might come as a real surprise to the country is that people can now purchase beef noodles online. One of the founders of "Niudafang" - an online beef noodle shop - is Deng Yubo, who was born in Lanzhou. After he graduated from Lanzhou University with a doctoral degree in math in 2011, he went to Beijing to take up a post-doctoral position at a key university. A friend once told Deng that the beef noodles of Lanzhou were so delicious that he always ate them two bowls at a time. The friend’s anecdote triggered Deng’s interest in beef noodles.
