The traffic of Songjiang District I have been studying in Songjiang District which is part of Shanghai for more than three years. The most impressive thing is that the traffic is very terrible to some degree. Last Friday, I left my college for the bus stop. It was two o'clock when I arrived at the bus stop waiting for the bus. And I knew the bus goes every twenty miniutes or even more. Then, I started playing my mobile phone. However, after half an hour, the bus I was waiting for still not came and I doubt whether it would pass this stop. I stood up and checked the board(where wrote the bus information). It proved that I was waiting in the correct station. What's more, my bus going past me in the opposite direction of the road further convinced me that I should continue waiting. As a result, I sat down went on waiting for the bus. An hour passed, still could not see the bus. I began worrying about it. I checked the WeChat Official Accounts and found that the bus to my surprise skip this stop. At that moment, I reminded that my roommates had told me that part of road was being fixed. Right now I went to the convenient store and asked the shop assistant whether the bus I was waiting for had changed the direction. It turned out to be true. And I had to walk to another stop to get on the bus. So, here is the question. Except the notice on the bus, where else can I know whether the bus has changed its direction? The WeChat Official Accounts is a real-time system,why doesn't it tell citizens this emergency? That's what my experience of the traffic in Songjiang District and I wish that it will be improved in the future.
