1. Tear the first vegetable into pieces by hand. Do not cut it with a knife or blanch it.

2. Heat the pan with cold oil. There must be more oil, double the amount for normal cooking, otherwise it will be easy to burn. Heat the oil slightly, add garlic, peppercorns, dried chili segments and sauté until fragrant.

3. Then add the kohlrabi and start stir-frying over high heat. It is best if you know how to use a spoon. After about 1.2 minutes, turn to medium heat and stir-fry continuously. Add the very fresh flavor and oyster sauce. The whole process takes 7.8 minutes. Okay, that's it.
