Who is the flight attendant of Harmony? Does the bus go straight?

There are generally two kinds of train attendants, one is to rest for six hours on a long journey, and the other is to rest for eight hours. This kind generally has no dormitory.

For some 8- 10-hour trains, their flight attendants arrive at the station to rest. This kind of rest time is longer, and there will be a dormitory after the station.

Good luck.
