Metro and bus codes地铁公交码

Metro and bus rides are usually a QR code in Alipay or WeChat, not a foreign bank card at the gate.

地铁公交通常是支付宝或微信乘车码，不是在闸机刷外卡。

Set this up after your wallet works. A mainland SIM is optional for this.

钱包能用之后再设。内地 SIM 卡不是必须。

Keep a little cash as a backup. Cards are not universal on local transport.

备一点现金。本地交通不是处处能刷卡。
