From Xiamen we want to visit Tulou & then to Shangrao

There is no direct train to visit. However, it is available to take a high speed train from Xiamen / Xiamen North Station to Nanjing first. From the Nanjing Station, there will be around 60 km from the Tulou Scenic Area. It is suggested to take a taxi directly, which takes about CNY 200 for a single journey.

There is no direct train from Nanjing to Shangrao, so you need to go back to Xiamen first and then take a high speed train to Shangrao. There are direct buses from Shangrao Station to Wangxian Cliff village at 7:30, 9:00, 10:00, 11:20, 12:40, 14:00, 15:20, and 16:30.

Thank you very much for the info. I believe that there is a bus from Fang Hu Bus Station in Xiamen to Yongding Tulou. Also buses from Xing Lin Bus Station.
Or by train from Xiamen North Train Station to Longyan then by car to Yongding for about 2 hours.
