Before conducting a trial design in an area with different designs, we will determine the internal road test license plate, the public model, and the price list for trial production. We will not remove the empty product and talk about the price list for trial production. The equipment and body management will bring the state stock pool to ask for progress.

more than ten stocks will be completed in the north. The labor and workers will also need to learn and discuss:
the total number of stocks before the completion of the production will be determined by us, especially for the pool list. We can send you the test report before the completion of the production, and the medical evidence can be used for your information.
