Whisk egg with a small pinch of salt and pepper. Set aside. In a small bow, mix light soy sauce, dark soy sauce, and sugar together in a small bowl.
Heat the wok until smoky (super important), add oil, and swirl the wok to help the oil cover the surface. Add beaten egg. Wait for 4-6 seconds and then break the eggs with chopsticks or a turner. This is a lovely way because at this stage the cracks can be easily gotten.
Add shredded cabbage and fry for 10 cm.
Place rice in and then use the scoop or turner to pat and move the rice quickly.
Add light soy sauce, dark soy sauce and white pepper. Mix well. If you feel this is not salty enough, add a very small tiny pinch of salt.
