@raynbow- The problem that you are having with food sticking when you cook in your wok is with your cooking methods, not the wok itself. Three important steps will help you create tasty meals in your wok without them sticking or burning.
First of all, you must make sure that you use enough oil to coat the wok pan. You can use your favorite cooking oil, just make sure that you swirl it around the wok and cover all areas of it before putting food in it. You should also avoid extra virgin olive oil, because it does not work well under the extreme temperatures necessary for wok cooking.
Next you have to make sure that the oil is very hot before you put food in the wok. If not, it will begin to stick as the wok continues to get hot during the cooking process.
Finally, once you put the food in your hot wok pan, you must keep it in motion to prevent it from sticking. Many cooks use a swirling motion of the wok while cooking, while others use a metal spatula or spoon to continually stir the food until it is ready to serve.
