I tell you, the best dough I have ever eaten is the best in Baoji, Qishan County, Yidian Town under Qishan County and Qinghua Town. I eat it every time I go to Tsinghua. If you are in the city, you can eat in Airport Street, not far from the railway station. Everything there is delicious, especially authentic, with chewy dough and delicious peppers. I drool at the sight.
