Crush all the garlic. Mince roughly and set aside.
Separate the kailan's stems from the leaves. Slice the stems thinly. Cut the leaves into 3 pieces. Add them into different bowls and set aside.
Cut the chilli into half diagonally for extra flavour.
Add 4 tsp of cooking oil to the pan over medium-low heat. Crack the eggs and cook them for 3-4 minutes for runny yolks. For firm yolks, flip the eggs and cook for another 30 seconds. Remove from the pan and set aside.
In a wok over medium heat, add the cooking oil and minced garlic. Fry for 1 minute, or until golden brown. Remove from the heat and set aside.
Add the salted fish and fry for 1 minute, or until almost cooked. Remove from the heat and set aside. Scoop out the excess oil, leaving about 2 tbsp in the pan. Remove the fish bones when slightly cooled.
Wear a mask and ensure the kitchen is well-ventilated. While the oil is still hot, fry the chilli for 15 seconds.
Add the kailan stems and continue frying for 45 seconds, or until they are well-coated in oil and have cooked slightly.
Add the kailan leaves. Stir fry for 1.5 minutes, or until all the leaves have softened and reduced in volume.
Add the salted fish and 3/4 of the fried garlic. Reserve the 1/4 for garnishing. Toss the ingredients together for 10 - 15 seconds. Optionally, add some reserved fish oil.
Switch off the heat. Dish onto a serving plate and garnish with the leftover fried garlic.
Serve with white rice, sunny-side-up eggs and a drizzling of fish sauce.
