How much is the coach from Jinan to Dongying? How long has it been? Which station goes to Dongying?

I often go from Jinan to Dongying by bus. I usually take a bus at Jinan long-distance passenger station, and sometimes I take the connecting station opposite the railway station. General modern Daewoo 50 yuan, insurance plus one yuan. From Jinan to Dongying, it usually takes two hours to take the expressway in the afternoon, and it usually takes three and a half hours to take Guangrao to Dongying at Linzi Expressway. It was already dark when the late bus got off the expressway, so it took about four and a half hours to walk slowly. Go to Dongying bus terminal, the one on the Yellow River Road. Not to the West Bus Station in Xicheng, nor to the East Bus Station in Dongcheng. Only go to the long-distance bus station.
