Sauté the garlic until soft, add the green beans, and stir until the beans change color.

Add the corned beef and a little water, stir.

Season with oyster sauce and sugar, taste it, and if it's not salty enough, add more oyster sauce until it tastes right.

Cover and let it simmer until the flavors are absorbed and the green beans are slightly tender, about 3-5 minutes depending on your preference.

Once the beans are tender to your liking, turn off the heat.

Enjoy with warm rice.
