Keep one reliable payment loop
Daily China runs on QR wallets. Treat cash as backup, not the primary plan. Re-test a small QR payment every few days if a card keeps failing.
- Confirm Alipay and/or WeChat can still pay a real merchant QR
- Keep a small RMB cash float for taxis, markets, and outages
- If a wallet fails: notify your home bank, retry SMS binding, then fall back to cash
- Read the payment guide when products or limits change
