Generally, there are group purchases of these two hot springs online, which should be released by travel agencies, and some write a one-day tour of hot springs and provide round-trip tourist buses; Without this group purchase, the first step to these two hot springs is to take a bus to Weihai Bus Station and Wendeng Bus Station.
Step two, if you go to Tang Bo, take bus No.2 at the bus stop outside the station. If you can't get to Tang Bo, please pay attention to ask the driver when you get on the bus. It seems that only cars running on the outer ring pass there. If you go to Tianmu, take a short walk to the lobby of Wendeng bus station and find Zhang's car, or just write the word "Tianmu" on Tianmu's car and ask the people at the station. This is safer.
Happy hot spring ~
