What service concepts should EMU strengthen?

The service concept of EMU is as follows:

People-oriented, customer first, be polite to others, like family.

example

On a moving train, one passenger had diarrhea, which prevented others from getting on the train. This often happens. Attendants should prepare some antidiarrheal drugs to take care of passengers and feel like family members. Passengers will be very grateful to the waiter for his love.
