If you chose the Taxi as your transport you can chose a local taxi company who you can recognize by how they look and that they have taxi written on them. This taxi is a little more cheap than DIDI. With the local taxi the price is based on a metered fare and a standerd starting price. You can pay with cash or with Alipay and WeChatpay. You can read more about these on the payment page. They also have their own app called DIDA you can download from the Apple Store or Google Play Store.
