Why pedicure is better than self-repair?

I studied a major. The reason why pedicure technicians are better than themselves is mainly because these technicians have received systematic professional training before they officially take up their posts. The requirements for technicians will be very strict. Without professional training, pedicure will be affected by body folding, so it is not as good as professional technicians after repair. Precautions for pedicure: When pedicure, you should first clean your feet in advance, and express your true thoughts in time during the pedicure process, so that the other party can adjust their posture at any time.
