The toll station from Weihai to Qingdao is Weihai-Wendeng North-Zetou-Nanhuang-Rushan-Rushan West-Haiyang-Xin 'an-Yangjun-Chiffon-Dianji (you can get off at this station and then go directly to National Highway 204, which is not far from Qingdao)-Huashan (you can also get off at this station and pay the toll.
So the conclusion is that toll stations can be collected from Dianji or Huashan.
Then I don't count the gas money, so I should understand.
