QuoteMaybe people could share their favorite noodle recipes from whichever region of china/ the world they are from....
The problem with that suggestion is that, in China (and, I think, most other places in Asia at least), the vast majority of noodle dishes, and certainly the most interesting, are only ever eaten in restaurants or, more likely, at small shacks or roadside places. Here in China, these places are highly competitive and do not give out their recipes.
This place is packed from early morning till late at night. I caught this picture just before the noon rush today.
Even if the recipes were available, still no one would make them at home. They are available on every street corner (there are five within three minutes walk of me, right now) for much less than you could make them at home.
The local favourite here, Luosifen, requires a soup base that takes hours to prepare and it wouldn't be economically viable to make it on a home basis. No one is going to spend hours and cash making something they can buy for next to nothing. These places sell 100s, if not thousands, of bowls of noodles every day.

Many of these places only do one or two dishes. You get to choose between round or flat noodles and there is usually a selection of condiments with which you can customise your dish. But that's it.
Condiments for your noodles - including various pickles, coriander leaf (cilantro), chilli flakes etc.
Most of the noodle dishes round here are soup based. I seldom eat 'chow mien', but when I do it's always different from the last time - even if I go to the same restaurant again. It is basically a 'use what you have too much of' dish for most restaurants.
Similarly, when people do cook noodles at home, they don't cook specific recipe based dishes. They may throw a few noodles into the soup left over from last night and eat it for breakfast or fry some up with other leftovers.
Anyway, here are some of the local noodle dishes.
