Travel from Shuyang, Jiangsu to Qingdao. The estimated tour time is three days, please recommend the route! Sincerely ask for recommendation, I will not give you less points!

There is a train to Qingdao in Shuyang. You can take that train directly. Arrive in Qingdao around 10 that evening, and you can stay near the trestle. Starting from the trestle is just your route. Climbing Laoshan Mountain seems to take two trains, 304 and 104. There should be a through train on the trestle. To go to Golden Beach, you need to take a ferry from the trestle to Huangdao, and then take a bus to Golden Beach. The ferry closes when the weather is bad. (zhanqiao park-Luxun Park-No.1 Beach-Badaguan-No.3 Beach-May 4th Square-Olympic Sailing Center. ) This is just a line. One day is not enough.
