Beihai (北海) is a smallish city in the south of Guangxi, by the sea, near the border with Vietnam. It's about two hours away from me and is seafood central. Nearly all the seafood and sea fish I can buy is caught there.
Like most cities here, it has it's own 'iconic' noodle dish. Rice noodles with clams.
The correct way to eat them is to put them into your mouth over and over until your bowl looks like this. (Do not eat the clam shells. Throw them on the floor.)
