Eyebrows are double-layered. This kind of eyebrows is called eyebrow crossing, which means that the eyebrows grow from the middle and split into two eyebrows. This phenomenon is not good, which shows that your character is rough, impatient and sometimes unreasonable. It is recommended to trim your eyebrows and make them slightly curved up and down (the eyebrows are not all the way up but a little curved down), which will help you to have good luck.
I hope it helps you.
