I want to advertise on Tricycle, who should I contact?

Look for the Baodi District Tricycle Management Office at the entrance of the Chengbei Police Station. Just give them your request or the printed promotional materials. They will be responsible for posting them on the tricycles and informing tricycle owners. The preservation of advertisements shall be supervised and inspected. (The prerequisite is to apply for registration and filing with the industrial and commercial department and the municipal appearance committee department)
