I have returned home: how do I follow up on something left in China?

At a glance

• Railway: use 12306’s lost-item service and search by train, station and travel date; a matching listing needs a claim inquiry. [1] [2]
• DiDi: reopen support in the account/entry point that booked the ride. Its China site lists Feedback@didiglobal.com and passenger hotline +86 400 0000 999. A 400 number may not connect from your overseas carrier, so use written support first. [3] [4]
• Hotel, attraction or restaurant: use the contact in your own booking or receipt and name the actual branch. Prepare the item description, last location, date, order/room/seat details and a reply email.
• The first-14-day plan below is a practical follow-up rhythm. It does not change the operator’s storage, reporting, shipping or insurance terms.

How to start from abroad

1. Day 0–1: reconstruct the last certain location. Write a short timeline and attach one useful photo or identifying detail. For a hotel, give stay dates and room number; for rail, train/date/coach/seat; for a car, order number and pickup/drop-off. Keep account access and your booking email available while the case remains open.
2. For rail, open the linked 12306 lost-item service, search found items, then register yours if no match appears. Registered users may report for themselves or passengers; the service also directs non-users to registration or 12306 phone support. Ask for a case reference and a written response if calling from abroad is awkward. [1] [2]
3. For a DiDi ride, open that order in the original app or mini-program and use its support. If you lost the booking phone, give the account phone number and ride details to support through a remaining channel. Use the China contact rather than an Australia or Latin America lost-item form. For a hotel or venue, ask reception or customer service to search the actual room, storage area or department.
4. When a match is reported, establish where the item is held and how ownership will be confirmed. Ask for a photograph and the collection options before arranging transport. Agree a local trusted collector, delivery to a named address, or international courier only if the holder can provide it. A found item does not automatically have an international shipping service.
5. Day 3–7: if the case is unanswered, follow up on the same reference and timeline. Ask whether a search happened, whether another department has custody, and when you should next contact them. If dispatch is agreed, obtain the tracking number and retain it until actual delivery.
6. Day 8–14: record one clear outcome: still searching, found awaiting collection, dispatched, delivered, or closed without recovery. If still open, keep the next action and date. Contact your insurer within its own reporting requirements if making a claim; this editorial window is not an extension.

If your situation is different

If you have lost a passport, use the existing lost-passport guidance immediately. A property search does not replace the issuing authority’s document process. If a device contains account access, deal with access through your device/account provider while the physical search continues.

If the found item contains batteries, liquid, food or other restricted contents, ask the holder and chosen carrier what can actually be transported and at what cost. If a friend collects it, agree the authorisation and identification the holder accepts. Do not assume the railway, hotel or driver will accept an informal message as the whole release procedure.

Common mistakes

• Sending the same vague request to several branches: identify the branch and last location so someone can search.
• Calling “found” a completed recovery: agree collection, then track dispatch and delivery.
• Waiting two weeks before opening a search: report promptly, then use the two weeks for follow-up.
• Using a different country’s support form: keep the case with the mainland operator that handled your booking.
