This is not the problem of the house, the most important thing is the safety of air drift and arch. The success probability of personal recognition is almost zero. Then let's take Wuxi as an example. It's hard to approve. You'd better ask an advertising company for help, or pack all the things for the company, which is convenient and worry-free. Let me tell you the price. Air drift and arch are around 500, and there may be approval fees. This is the standard of Wuxi, because I am from an advertising company, so I still know this piece very well. I hope I can help you! ! thank you
