At present, the driving test subject is parking on the second ramp. I always press the line, either white or yellow. I think there is something wrong with what the coach said. what do you think?

Are you talking about the right route? Everyone sees things differently. The coach will usually ask you to keep your posture first, and then let you watch the rain blow to a certain point on your arm, which should always be facing the white line. But there is a more accurate point of view. You can look at the right rearview mirror and see the distance between your car and the white line. You can't go wrong.
