Thanks for this great video! Are 油面 and 莜面 the same type of 面 ? I'm used to see 莜面 but those are quite different from those shown in the illustration in the video. 莜面 are made of oat and they are light-brown in color. As for the the shape, it's typically small rolls placed vertically in a steam basket, but there are many variants. Those "noodles" (I admit the shape is rarely 'noodle-like') are frequently served in an area between Shanxi and Inner Mongolia. I also love 钢丝面, I really think an italian would like them for being 'al dente'.
