I booked a return ticket from Shanghai to Jinan in Jinan. Can Jinan go out?

Yes, there is a handling fee. I don't know whether you are talking about a plane or a train. If it is a train, there is a free way to get tickets, that is, after booking tickets online at 12306, pick up tickets at Shanghai Railway Station with the order number and pick up tickets before the train you booked leaves. This can avoid handling fees.
