Shahe fen or he fen or hor fun or guotiao are traditional Chinese noodles originating from Shahe in Guangzhou. In order to make the noodles, rice is soaked, ground into a paste, steamed, and cut into long and thin strips.
These broad noodles are white in color, while the texture is slightly slippery, elastic, and chewy. They're often stir-fried with meat, veggies, oil, and spices for a dish called chow fun. Shahe fen don't dry or freeze well, so they're typically bought in fresh or dried form.
