Relatives have done catering and go to the physical examination every year. Let's say a few things briefly. First, take photos, then X-ray the liver, and then draw blood. The most troublesome thing is to attend class, listen to DVD about hygiene for half an hour, and then have a small paper for you to answer, but it is very simple. Oh, before listening to DVD, you should check whether your nails are long. If it is long, cut it off on the spot, and the other party will provide nail clippers.
The whole process takes less than an hour, if there is no need to queue up.
Then you can get the license in a week.
