On the Harmony train and the high-speed rail, every half hour, a cleaner comes to collect the disposable envelope garbage bag, even if the garbage bag has just been opened.

This is the service standard of high-speed trains, and environmental protection should be jointly built by the whole people. If there is less garbage, try not to take the garbage belt with you. Most of a passenger's garbage is related to food. If the journey is short, don't eat in the car. The food you bring and the food you buy on the bus are packed, so you don't need it on the high-speed rail. As for the conductor cleaning up the garbage, we should look at it according to the specific situation and ask the passengers if there is any new garbage. If there is, we will collect it next time. Are you satisfied with this answer?
