I have never been on a train, for fear of being laughed at. Experienced people to explain! thank you

It's okay. I used to be like this. You just need to sit a little longer. If a person is afraid, you can ask relatives and friends to take you. If one doesn't have to be afraid. First of all, buy a ticket, go to the station one hour in advance, check in at the ticket gate and go through the security check. Look at which window you are in, and then look at which car and seat you are in. Just go straight when the bus comes, if you don't know by then. You can ask the railway station staff, don't worry. Don't worry if you don't catch the bus in time. You can return this ticket and exchange it for a new one. If you feel trouble and don't get carsick, you can also take the bus.

I hope I can help you.
