Method

1. 1 Pick only the tender leaves and shoots, discarding the tough stems as they won't soften quickly enough.
2. 2 Wash and drain thoroughly; if there is still water in the vegetables, the pan will cool down and the vegetables will release their water.
3. 3 Heat the pan until it smokes, then sauté the crushed garlic for exactly 20 seconds.
4. 4 Add all the vegetables and stir-fry over the highest heat for exactly 60 seconds.
5. 5 Sweet vegetables are very tender, so they'll be gone in 60 seconds; otherwise, they'll become mushy and slimy.
6. 6 Season with oyster sauce mixed with cornstarch, then toss the pan for 20 seconds and sprinkle with white pepper and chili.
