Combine water, five spice, ginger, garlic, salt, soy sauce, scallions, & vermouth into large pot. Bring to vigorous boil & slowly insert duck.
Bring liquid & duck to a boil again & immediately turn heat to low. Simmer, covered, for 1-1/2 hrs. Remove duck from liquid & let cool, reserving stock for use in Sauce. Cut the duck in 1/2 & remove bones. Brush Batter over duck halves & allow to dry. Heat enough oil to cover duck to 350° F to 375° F.
Carefully slip the duck halves into the oil. Fry for 3-5 min. or until golden brown & crisp. Remove from oil & drain on absorbent paper. Cut duck into manageable strips & arrange on platter. Serve with Sauce. Batter: Mix all ingredients together. SAUCE: Pour duck & chicken stocks into heated saucepan.
Bring to a boil and add cornstarch mixture. Cook, stirring constantly, until sauce thickens. Turn off heat and add Grand Marnier and scallion.
