Needless to say, Linfen goes to Taiyuan.
The trips from Taiyuan to Shenyang 1 138 or 1 172 are all ordinary air-conditioned cars.
1 138 24 hours
1 172 20 hours and the fare is cheaper than 1 138. Hard seat 140.
It is more expensive to go to Beijing, because the train fare from Beijing to Shenyang is relatively high, and most of them are bullet trains. It is difficult to buy tickets for non-motor trains. I won't go to Beijing at the highest.
