Hello, can we reach Yunshuiyao old village from xiamen by public transport ?

Yes, you can take high-speed train from North Railway Station and get to Nanjing Railway Station first. The duration is about 40 mins. And the ticket fare of second class seat is CNY22.5 and first class seat is CNY26.5. After arriving, for your convenience, just hire a private car to get to the scenic area directly. :)
