The ID photo requires a bareheaded (bareheaded) front photo. Such a photo can have bangs, but it can't cover the face or cause shadows, and the five senses should be exposed.
When taking this photo, you need to sit upright, open your eyes naturally and look straight, your ears are symmetrical, your left and right shoulders are balanced, and your head and shoulders should be straight, neither too big nor too small, accounting for 2/3 of the whole photo.
