How much does it cost to press an advertising machine for the elevator in Lanzhou?

This focus is really strong, you can consider changing places. Airports, stations, shopping malls, hospitals, and now many media companies have settled in. There are also advertising machines, which are mainly divided into stand-alone and network. Stand-alone machines are all updated by manpower one by one. Network can remotely and centrally control the convenience of publishing operation, but network problems should be considered. One is to talk with the property about using the property network, or use 3g directly. Some large media companies will choose 3g, and they will negotiate the price with network operators. If it is the property side, you have to pay a certain management fee, and the details are to be discussed.
