The No.4 line subway is going to be started in test operation on 28th September. There were 200 removal citizens living along the No.4 line have become the first passengers in test operation. During the whole journey, the attendants will answer tht passengers' questions, squatting there with heads up. It is said that this is one of the service norms to show respect to the passengers and ensure their security. During the Paralympics, the staff working in the Paralympics Village adopted this service for the players so as to communicate with them based on the same level, which shows respect to the hearer and has gained its reputation. However, since there is always a flow of people in the subway, whether 'squatting service' will be appropriate and varied out effectively has aroused great controversy. My friends, what is your opinion?
