The two brothers took a long-distance train for the first time. My brother goes from Yantai to Chengdu, and my brother goes from Yantai to Wenzhou.

I can help you solve it from Yantai to Chengdu! My own personal experience! I went to college in Chengdu for four years.

There is only one train from Shandong to Chengdu, which is K205(8). About 42 hours, arrive in Chengdu around 9 am, which is Qingdao Railway Station! The departure time is afternoon. I am from Yantai, too. I always take this bus! Through train comfortable berth ticket around 500 yuan, ordinary ticket around 280 yuan.

To Wenzhou, Zhejiang, I suggest you transfer to Shanghai. There is a bullet train from Shandong to Shanghai. Soon. However, in this case, the toll may be a bit high.

Another option is to transfer to Jinan, one is K 10 1 from Beijing to Wenzhou, and the other is K55 1 from Harbin to Wenzhou. My suggestion is to change trains in the province. Speaking in a dialect outside is far from the local dialect, which is easy to be noticed by scammers!
