1, you can buy train tickets online and pick them up all over the country after purchase.

2. You can go to the ticket window of the railway station to buy tickets, and each ticket will be charged the handling fee for the off-site ticket in 5 yuan.

I just checked that there is no through train from Ningbo to Yongxiu, so I have to change trains, so I need to buy a connecting ticket or a through ticket.
