What should I wear to travel to Jinan and Qingdao in mid-May? How's the temperature? What tourist attractions?

In mid-May, the temperature in Jinan is generally around 25 degrees, so you definitely don't need to wear autumn clothes and trousers, just add a thin coat and summer clothes, and Qingdao will be 2-3 degrees lower, with little difference. Baotu Spring, Qianfo Mountain and Daming Lake, the three famous places in Jinan, are must-see. None of the three scenic spots is far away. You can start from the north gate of Daming Lake, exit the southwest gate to Baotu Spring, and stop at quancheng square and Furong Street. Then go to Qianfo Mountain. If it goes well, it will take 1 day. In the next two days, you can go to the southern mountains to play. Jiuru Mountain in the southern mountainous area is really good, with artificial waterfalls, but the ticket price of 120 is on the high side, and Hong can do it now. Tulips are beautiful and the scenery is good. Tickets for 60 are still benevolent. If you want to go to Qingdao, Zhanqiao and May 4th Square are the must-see places. I suggest you have time to go to Laoshan Mountain and Underwater World.
