Yes, what is most important is the stirring action: you should use your wrist to scoop, flip and push the food continuously. A wok ladle has a curved end that is designed to get right to the bottom of the wok so that it is easy to flip the food over when stir-frying. Whether you use a wok ladle or a wooden spatula, every bit of food in the wok must be moved about constantly, over the entire surface of the wok. Most foods need no more than 5 minutes cooking, less with intense heat.
