How do I supplement my train ticket on board?

Find the conductor (列车员), show ticket and passport, and pay the difference by cash, WeChat, Alipay or sometimes card.

What if I have no valid ticket?

You may be charged a penalty plus the fare difference. Always supplement before the conductor finds a gap.

You need to add a ticket on board

If your ticket only covers part of the trip, find the conductor (列车员) and pay the difference.

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.

Fastest fix, free: Find the conductor (列车员), usually near the middle of the car, show your ticket and passport, and pay the difference.

Every case shows the diagnosis and the first step - free. The full step-by-step fix for this exact case, the decision tree, and the offline kit are $9.99.
