Wash Chinese chives thoroughly, then shake off any excess water. Cut them into 1-inch (2.5 cm) long sections.
In a big bowl, lightly beat the eggs until the yolks are well incorporated with the whites. Add the chives and salt to the eggs. Stir to mix well.
Heat oil in a wok, or a skillet, over high heat until slightly smoking. Swirl the oil to coat a larger area, then pour in the chive and egg mixture.
Let the eggs puff up undisturbed. As soon as the bottom part turns solid, push the block to the side of the wok, allowing the runny mixture to flow to the center to cook.
When most of the mixture has solidified, toss and break any large lumps into bite-sized pieces, then transfer the dish out immediately.
