The cross-harbour tunnel is about to open. Does anyone know which buses are available from Qingdao to Huangdao? Great gods, help!

Hello, I'm not sure about some specific situations. But I can tell you the general situation: On June 28th, the tunnel bus was opened, and citizens can take Qindao Link, but the elderly can still enjoy preferential treatment. In fact, I think the biggest convenience is that I can travel freely in the future, and I don't have to be affected by the ferry anymore. I can go to Qingdao with my friends on weekends. Recently, I heard from a friend that there seems to be a kind of tour package called Qingdao Travel One-Ticket Pass (Baidu, you know). I hear it's very good. One ticket can go to six scenic spots, and the time can be arranged by yourself. That's so cool. Hehe, I will buy some tickets with my friends this weekend. . . There are four main routes for bridge and tunnel bus: Line 1: Zhongshan Park-Xuejiadao Beihai Shipbuilding Industry; Sites along the way: Shandong University of Science and Technology, Aucma Industrial Park, West Coast Hospital, Qingdao Binhai College, East Gate of Bonded Port Area, Huangdao Transportation Bureau, Huangdao Long-distance Station, Huangdao District Government, Wharf Leisure Village, Qingyun Mountain Road, Beichuan Staff Apartment, Beichuan Heavy Industry, Wuchuan Heavy Industry, Tuandao, Xizhen, Qingdao Railway Station, Municipal Hospital and Qingyi Affiliated Hospital.
