支付
只用支付宝够吗，还是也需要微信支付？
支付宝一直能用，直到苏州一家面馆只贴了微信绿色二维码——我不得不请酒店帮我下单。现在我两个都用。
快速结论
Alipay worked until a Suzhou noodle shop showed a green WeChat-only QR—had to ask my hotel to order for me. Now I run both.
详细回答
下一步
Enable WeChat Wallet tonight → bind card → do not assume Alipay scan works on green QR stickers.
怎么做
Finish Alipay bind first if you prefer that order.
Open WeChat Wallet (chat alone is not Pay).
At next stall, check sticker color/logo before you queue.
常见坑
Installing WeChat for chat but skipping Wallet until a shop refuses you.
Scanning a green WeChat QR with Alipay and blaming "China is broken."
Thinking one successful Alipay payment means 100% coverage.
