Why is there a bus with a conductor in Jinhua?

In Jinhua's public transport system, some bus lines are still charged by the conductor. This is mainly because the operation scale of these lines is small, and the use of electronic ticketing system will increase the operating cost, and the passengers on these lines are mostly elderly people or people who are not familiar with electronic payment, so it is more convenient for them to use ticket sellers to buy tickets and take buses. In addition, the conductor can also provide some services and help in the car, which increases the satisfaction of passengers. Of course, with the popularization of electronic payment technology and the continuous expansion of bus lines, the number of conductor buses will gradually decrease.
