What is the cheapest way to take the train route from Suzhou to Xiamen, and the time can be shorter (you can change trains halfway)

If you want a shorter time, I suggest you take the bullet train.

Take D3 13 at 6: 47 to Shanghai Hongqiao at 7: 20, and take the second class seat to 26 yuan.

At 9: 43, Shanghai Hongqiao takes D3205 to Xiamen 17: 05, and the second-class fare is 348 yuan. It only takes 10 hour to transfer, but the fare is 374 yuan.

If you want to be cheaper, I suggest you sit like this:

Take K527 18:43 to yingtan at 5: 1 1, and the fare is 103 yuan.

Transfer to K307 at 6: 32 to Xiamen 19: 27. The fare is 94 yuan, including the transfer time of 24 hours, but the whole journey is only 197 yuan.
