The raw materials and technology of flat rice noodles are very simple, mostly cauldrons and flat rice noodles.

First, cook a large pot of stock, and then cook flat vermicelli in the pot, and then stew tofu slices, pig blood slices and vegetables. What needs to be pointed out here is that flat vermicelli should be soaked in broth for 4~6 hours before cooking, so as to ensure that flat vermicelli can better absorb the taste and nutrition of broth.
