This technique is an age-old method of making noodles in which the dough is kneaded with a bamboo pole that's ridden kind of like a see-saw. The long and exhaustive process creates a unique texture in the noodles that can’t be achieved any other way. Unfortunately, there are not many places left that still do it, with Lau Sum Kee in Sham Shui Po being one of the last bastions of bamboo pole noodles.
