You can also talk directly with the taxi driver (owner), but it is more complicated. But in this case, you can save a lot of advertising fees, and the advertising fees collected by the transportation management will not be given to taxi drivers. It is just an administrative means, and it is forced to install it under the slogan of unified coloring (some stubborn drivers refuse to install it, and the transportation management can do nothing), making a big profit from it. Whether you talk to the transportation manager or the driver directly, you made the overhead light.
As long as you discuss with the transportation management first (or simply leave it alone and try to find a way when it interferes with you), put the overhead lights with advertisements (such as long and wide overhead lights, which are eye-catching and meticulous, but expensive) in places where taxis often stop to entertain guests (such as stations, cultural palaces, hotels and other places). It will only take a few minutes to change the ceiling lamp, which will not delay the business), and the old one will be replaced with a new one (the ceiling lamp will turn gray and discolor after a long time). Anyway, drivers don't have to spend money (it costs 5,60 yuan to buy a small ceiling lamp), and most of them are willing to change it. As for the advertising fee you mentioned, the advertising fee charged by the transportation management office or the taxi company to which the vehicle belongs will not be given to the owner, so I tell you that as long as the transportation management office or the taxi company to which the vehicle belongs does not look for tragedy (they may find reasons to stop you from taking their money), you will still make a profit.
Anyway, I (have been in this business for several years) change the lights as soon as I have them. As for what others think, I don't know whether to change it (90~95% should be changed, except for some people who like to wrangle).
I hope you have a wonderful trip! ! !
