Cut each squid body in half lengthwise. Using a very sharp knife, lightly score the inside of the bodies in a crisscross pattern. Cut the squid into 11∕2-inch squares and the tentacles into 2-inch pieces.
In a 2-quart saucepan bring 1 quart water to a boil covered over high heat. Add the squid and blanch 10 seconds or until the squid turns opaque and curls. Drain well in a colander, shaking out all the excess water. Set the squid on paper towels and blot dry to remove excess moisture. In a small bowl combine 1 tablespoon of the broth, oyster sauce, soy sauce, and dark soy sauce. In another small bowl combine the sesame oil, cornstarch, and the remaining 1 tablespoon broth.
Heat a 14-inch flat-bottomed wok or 12-inch skillet over high heat until a bead of water vaporizes within 1 to 2 seconds of contact. Swirl in the peanut oil, add the fermented black beans, scallion, and garlic and stir-fry 10 seconds or until the aromatics are fragrant. Add the onions and ginger and stir-fry 1 minute or until the onions just wilt. Add the bell peppers, sprinkle on the salt and pepper, and stir-fry 30 seconds or until the bell pepper begins to soften. Add the rice wine and stir-fry 20 seconds or until just combined. Add the squid and snow peas to the wok, swirl in the soy sauce mixture, and stir-fry 1 minute or until the snow peas are bright green. Restir the cornstarch mixture, swirl it into the wok, and stir-fry 30 seconds or until the squid is just cooked.
