Lo mein, dan dan, biang biang, lamian, chow mein — every major Chinese wheat noodle, explained. The most regionally diverse noodle cuisine on earth.

China has the deepest regional noodle variation on the planet. Northern China is wheat-growing country with a 4,000-year tradition of hand-pulled, hand-cut, and machine-extruded wheat noodles. Southern China is rice country with rice noodle dishes (covered in Rice Noodles Explained). Western China (Sichuan, Shaanxi) has its own wild noodle traditions — numbing-spicy dan dan, hand-slapped biang biang.
This pillar focuses on Chinese wheat noodles — the northern and western traditions that gave the world hand-pulled lamian, knife-cut dao xiao mian, and the bold flavors of Sichuan and Shaanxi cuisine.
The dishes from different regions are nearly different cuisines. Don't expect Cantonese lo mein and Shaanxi biang biang to taste like the same family.
Chinese noodle cuisine predates Japanese and Korean noodle traditions by 1,500+ years. Wheat noodle archaeology in China goes back 4,000 years. Lamian (hand-pulled) techniques originated in northern China and spread to Japan (becoming ramen) and Korea (becoming aspects of ramyeon and Korean lamian).
