Is there the cheapest and fastest train route from Shanwei to Dalian?

it's inconvenient to get from Shanwei to Dalian.

First, go to Shantou, and then Shantou to Dalian. The first choice is to fly. The full price of the air ticket is 185. I don't know when you will come. You can find a discounted air ticket online. If you get a 6% discount, it will be more than 1.

So will the train, Shantou-Guangzhou-Shenyang-Dalian or Shantou-Beijing-Dalian.
