Boil hot water, put the steaming rack in the wok and pour in the boiling water into the wok. Put the stove in high heat to keep the water boiling.

Now you can carefully put the steam fish on the steam rack, cover the wok.Depending the strength of your stove, you can turn down slightly the heat after the first 2-3 mins of steaming.

When it is almost closed to 7 mins of steaming, you can heat up the cooking oil in a saucepan, make sure the oil is hot enough.

When the fish is cooked, remove the plate from the wok or steam pan.Then pour in the hot cooking oil very slowly on the fish as you will see the oil sizzling.

Finally you can add the soy sauce to the fish and serve immediately.
