Gather and prep all ingredients. Wash the vegetable. Kailan or chinese broccoli has a very hard stem. Lightly crush or bruise the stems. Then cut and separate the stems and the green leaves (pic).

Heat 3-4 tablespoons of neutral oil in a pan. Add minced garlic and sauté until it turns lightly golden. Add the stems and cook for a minute or two until it turns bright green. Add a pinch of white pepper powder. Stir again.

Add the leaves. Stir for few seconds over medium high heat until the leaves are wilted. Add oyster sauce & sesame oil. Stir until the greens are cooked, for about a minute. Taste and adjust seasonings accordingly or add salt to taste.
