How can I make Chili noodles fragrant and delicious?

Put the pepper noodles into a bowl, pour the oil into the pot, and when the oil temperature is enough to mix the pepper noodles, pour a little on the pepper noodles, then heat the oil to 60% to 70% heat, mix the pepper noodles without pouring a little, then heat the rest to 80% to 90% heat, and then pour all the pepper noodles. At this time, the pungent smell came to the nose.
