What you'll see
If you boarded but your ticket does not cover the whole journey, you must extend it on board:
"Ticket incomplete" · "Please supplement fare"
车上提示为:车票不完整 / 请补票
Error-text level: L2 (observed wording). Exact on-board text is being verified.
Why it happens
A partial ticket is valid only for the booked segment. The conductor (列车员) can extend it for the difference, or a penalty applies if you have no valid ticket.
