According to my knowledge, it seems that a popular carpooling platform for traveling from Taiyuan () to Wutaishan () is Didi Chuxing (). You can try searching on the app or website by typing in your starting point (Taiyuan) and destination (Wutaishan), as well as your preferred travel date and time.
Alternatively, you may also want to consider other carpooling platforms such as:
- Shouqi Limousine & Touristic Auto Group ()
- Jingzhu Bus Service ()
