Rinse and soak the noodles in the water, per the package instructions. Drained and set aside. Mix all the ingredients in Seasonings in a small bowl. Stir to combine well.
Heat up a wok on high heat. When the wok is fully heated, add the oil into the wok. Wait for the oil to be heated.
Loosen the noodles and add them into the wok, use a pair of long chopsticks to stir and toss the noodles. Add the Seasonings into the wok, and use the chopsticks to combine well with the noodles. Continue to toss and loosen the noodles with the chopsticks. Add the bean sprouts and yellow chives into the wok, and stir to combine well. As soon as the bean sprouts and chives are cooked (but remained crunchy), turn off the heat, dish out and top the noodles with some white sesame seeds. Serve immediately.
