The lower eyeliner should be drawn from the outer corner of the eye, and 1/3 of the entire outer eyelid should be drawn outside the root of eyelashes, with slightly thicker lines. When it reaches 1/3, it turns to the inside of the eyelash root, and the line becomes thinner until it reaches the eye. These are the notes that my image design teacher copied for us. In fact, the actual operation need not be so troublesome. The back of his upper eyeliner is actually used to stick false eyelashes. Now, according to the above, try first. Also, mascara is zigzag and should be brushed from the root. According to my personal experience, when you finish brushing the Z-shape from the root, you will brush it straight in front, and so will the hair under your eyes.
