Contact and corrections

Public contact is not currently open

We do not currently publish a contact email or accept messages through this site. There is no support form, message inbox or response-time commitment here.

Please do not send personal information to someone claiming to offer nihaonana support through an unrelated account. This page is the reference for our public contact availability.

If a guide does not match what you see

Check the guide’s source-review date and open its cited source. Product terms, account requirements and travel rules can change after a page is reviewed. Current instructions from the responsible organization take precedence over an older preparation note.

Keep the page URL, the statement in question and a current primary-source link for your own reference. A successful or failed transaction is useful context, but it does not establish a rule for every traveler.

Get help from the service involved

• Cards and payments: contact your card issuer or use the support channel inside the official Alipay or WeChat app. We cannot view or change your card account.
• Mobile data: use the support contact in your eSIM order or the provider’s official app. Save installation instructions before departure.
• Bookings: contact the operator or booking channel shown on your confirmation. We do not hold reservations or process refunds.

Never send card numbers, CVV/security codes, passwords, verification codes, activation QR codes or passport scans to a person claiming they need them to review a nihaonana guide.
