Cars and planes are generally not discounted (except those that have been discounted). Under normal circumstances, train tickets can be discounted, and you can enjoy half price with the admission notice, but it is limited to basic services. For example, hard seat 200 can be 100 after discount. But if the soft berth is 500, in which 300 yuan is an extra service, there is only the basic service 200, that is, 400.

I hope it helps you. I wish you a pleasant journey and hope to adopt it. Thank you!
