With the continuous development of the Internet era, mobile payment has entered our lives. After swiping the credit card, Guangzhou Metro also joined WeChat to pay for tickets and Alipay to recharge its own Yangchengtong.

The service in the subway has become more and more perfect. There is air conditioning in the subway and a rest place on the platform. Moreover, the subway won't wait long because the waiting time is relatively fast. But there are also some areas that can be improved. For example, there are fewer toilets in the subway, only some relatively large subway stations, Guangzhou Railway Station, South Railway Station and some main stations. Adding more toilets can better enable some citizens to cope with emergencies.

In addition, because there are many people in Guangzhou, people have to wait for a long time and the rush hour is crowded, so it is more convenient for us to take more trains at this time.
