For this Henan dish, use the whole canned shoots rather than ones that have been pre-cut, so you can cut them to the shape or size you like. They have already been processed and boiled, so the cooking time is not lengthy.
Cut the bamboo shoots into bitesize chunks (or slices, if you prefer) and soak them in cold water for 30 minutes. This will reduce the scent and taste of the pickling liquid from the canned shoots.
Heat the oil in a wok, add the garlic and stir-fry for 2 minutes. Drain the bamboo shoots and add them to the pan. Stir-fry for 2 minutes, then add the spring onions
