Here, Lu Tong Longka will send an OBU electronic tag installation certificate. As long as you get the card, you can go through the card opening formalities at CCB outlets, and then get an OBU installation voucher at the outlets at the same time. Finally, take this installation certificate, ID card, driving license and Lu Tong Longka to the ETC customer service center of each city highway bureau to install OBU for free. If the person at the outlet says that it needs to be handled after opening the card at the outlet, the voucher cannot be installed for you immediately. I think it may be an installation voucher that has just been issued. I will give it to you after applying to the branch office. By the way, Qingdao, Yantai and Weifang are not allowed to participate in this activity.
