The method of dressing raw or cooked-and-cooled ingredients with seasoning and serving them cold.
Cold noodles are noodles cooked, cooled in water and tossed cold with a sauce of soy sauce, vinegar, chili oil or sesame paste, often with vegetables such as shredded cucumber. Shanghai, Sichuan, Xinjiang, Wuhan, Jingzhou (Shashi) and Taiwan each have their own versions. A 2025 article recounts that Du Fu made lengtao in Kuizhou in 767, working locust-leaf juice into flour, cutting the dough into noodles, boiling them and cooling them in cold water. Lengtao is an old cold noodle dish; today's liangmian has no established place of origin, and no dated record or direct link to lengtao was confirmed.

Legend has it that in the Tang dynasty Empress Wu Zetian burned her tongue on hot noodles, and some people mention this story when they talk about where cold noodles came from.
Told in: A popular tale, told in a Qianjiang Evening News article of August 17, 2016 that gives no source for it, so it is treated here just as a tale.
This is a simplified home version, not the traditional restaurant method.
This is the simpler way I make it at home, with dried spaghetti-style noodles that many kitchens keep, so it is an adaptation and not the traditional cold noodles of any one city. The amounts of soy sauce, vinegar, chili oil and sugar are those of the sour spicy cold noodles recipe, halved; the cucumber and carrot come from the cold sesame noodles recipe; the other amounts are my own choices at home. Both published recipes are adaptations too, one made with spaghetti and the other with peanut butter.
Ingredients
Dried noodles (spaghetti or wheat noodles) 170 g
Light soy sauce 25 ml
Rice vinegar 25 ml
Chili oil 7 ml (about half a tablespoon)
Sugar 6 g (about half a tablespoon)
Sesame oil 5 ml
Garlic 1 clove, mashed
Ground Sichuan pepper a small pinch
Noodle cooking water 2 tablespoons, kept back for the sauce
Cucumber half, shredded
Carrot 1 small (about 50 g), shredded
Scallion 1, chopped
Steps
Bring a large pot of water to a boil and cook the noodles for the time printed on the package. Before draining, scoop out 2 tablespoons of the cooking water and set it aside.
Drain the noodles, rinse them under cold water until they are completely cool, drain well and shake them loose.
In a large bowl, stir together the soy sauce, vinegar, chili oil, sugar, sesame oil, garlic, Sichuan pepper and the saved cooking water until the sugar dissolves.
Add the noodles, cucumber, carrot and scallion, toss well, taste, add a little more soy sauce if it seems flat, and serve right away.
Tips
I drain the noodles very well after rinsing, because water left on them thins the sauce; this is my own habit.
I start with a little chili oil and add more after tasting, because everyone's heat limit is different.
