Change (改签) to another train, or refund (退票) with a fee that shrinks the earlier you act.
Refund fees shrink the earlier you act.
What you'll see
If your plans changed, the app lets you change or refund — with a fee that depends on timing:
"Change not allowed" · "Refund fee applies"
中国 App 里显示为:不可改签 / 收取退票费
Error-text level: L2 (observed wording). Exact in-app strings are being verified.
Why it happens
Refund fees are 5% over 48h before, 10% at 24-48h, 20% under 24h. Change (改签) to another train is usually free of a separate fee but subject to fare difference.
Fastest fix, free:Open the booking, tap Change (改签) to pick another train, or Refund (退票) — act early to cut the fee.
