核心观点
**Yes—as backup, not as your main wallet.** In tier-1 cities, daily spending is mostly **Alipay / WeChat Pay**. Still carry about **¥200–500** in **¥10 / ¥20 / ¥50** notes for when **both apps fail**, **metro machines** glitch, **temple donations**, or **small rural vendors**. Cash does **not** replace setting up mobile pay.

Detailed Answer
Read this if you are deciding how much RMB to carry—not how to bind Alipay (payment stack).
Urban China is QR-first (English.gov.cn). Tourists who only carry cash will struggle at many street QR stalls. Tourists with zero cash risk getting stuck when apps and card fail on the same afternoon.
How much (starting points)
| Trip | Suggested cash buffer |
|---|---|
| 3–5 days, Shanghai/Beijing only | ¥200–300 |
| 7–10 days, two cities | ¥300–500 |
| Rural / multi-week | ¥500–800 + ATM plan |
Prefer small denominations—vendors may refuse to break ¥100 for a ¥12 snack.
When cash beats QR (specific)
| Situation | Why cash |
|---|---|
| Both wallets down + card declined | Immediate ride/meal while you fix apps on Wi‑Fi |
| Metro ticket machine | Some hubs still take cash when QR gate errors |
| Temple donation box | Often cash-only |
| Old scenic stall | Occasional cash-only (rarer in tier-1) |
When cash does not help
- Merchant shows personal QR on phone at airport—use official transport, not stranger scan
- You have not set up any mobile pay—fix wallets first (payment stack)
适合谁
- “Should I withdraw RMB before flying?”
- Cash-only planners (usually a mistake—set up QR first)
- Temple / rural legs after big cities
下一步
- How to pay in China — primary stack.
- Payment failure after landing — order of operations.
怎么做
Set up Alipay and WeChat Pay first
Carry small denominations
Use cash when both apps fail or at temples

常见坑
Cash-only planning
Only ¥100 notes
Zero cash with untested apps

常见问题
Can I survive on Visa alone?
Some chains/hotels—yes; street-level China—no; use mobile pay + cash buffer.
Airport exchange?
Convenient but often poor rate—exchange only what you need for day one.
