Problems solved by technology

[0002] In modern times, cars have become an indispensable means of transportation for people. As there are more and more cars on the road, it is easy to cause traffic jams on certain road sections, and the passengers on the cars will become emotional because of the long wait. , it is easy to cause friction or quarrel with the driver, and modern enterprises often promote their own products or the cultural value of their own enterprises, but due to the high price of advertising on TV, the coverage of the masses is not good, and the publicity effect required by advertisers cannot be achieved , and wasting time and money in vain, based on the above shortcomings, it is particularly necessary to install a car projector that can be compulsorily advertised for specific groups of people in the car
