What will the weather be like in Qufu/Tai Shan/Qingdao in early March? Thankyou

From Qufu Long-distance bus station, you can find frequent buses for Taian.
From Taian, you can take bullet trains for Qingdao.
From Qingdao Sifang Long-distance bus station, there are buses for Qingdao. To reach Shanghai, it is suggested to fly.
You can take a thick coat and a thin sweater in early March, because it is still cold during that time with an average temperature around 4 to 5C.
Hope this time the information is useful for you.
