First, prepare a photo of your own car, which must be your own car, and the camera angle should be able to see the license plate number and the whole body. Then, find "registration" in the column of "online parking lot" and fill in some basic information of your car. Freight vehicles can also fill in the freight quotation and submit it finally. It will be approved in about one day. If it is a general registration (that is, the vehicle information is "randomly sorted" after review), it is free. If you want to rank high, you need to pay a fee, and it seems that the fee is not high.
That's basically it.
