Hi,there
You mean Rizhao of Shandong? If so, it will be a little hard for you to get to Shanghai. There is no direct bus or train or flight between Rizhao and Shanghai, you must transfer, either at Dongdao by bus or by train. Then it is easy to get from Shanghai to Beijing, either flight or train. You should decide which section of the Great Wall in Beijing to visit first and then get to know the transportation.
Anyway, wish you a nice trip in China.
