According to the query on NetEase, in January 2016, Shaanxi Youpo Noodles and Roujiamo were selected into the fifth batch of intangible cultural heritage list of Shaanxi Province.

Youpomian is a local specialty food in Shaanxi. It is said to have a history of more than 3,000 years. In fact, Youpo Noodles existed as early as the Qin and Han Dynasties, but at that time they were not called Youpo Noodles, but soup cakes.
