The Chinese high-speed rail management department introduced quiet carriages on many routes at the end of last year. In these carriages, passengers are required to keep their voices low, wear headphones, and turn off the speakers when using electronic devices. Some people welcome these regulations, believing that it will help ensure a peaceful journey. They think that this requirement will create a more civilized environment and encourage passengers to follow public order. However, there are also people who oppose this service, believing that it means people do not need to be quiet in non-quiet carriages. For them, the key to solving the problem is to require all passengers to be polite and considerate in all carriages.

In my opinion, introducing quiet carriages is a positive move. On high-speed trains, especially during long journeys, a quiet space can allow passengers to rest and relax, improving the comfort of the journey. This also helps improve the quality of public transportation and promote passenger satisfaction. However, I also agree that all carriages should require passengers to be polite and considerate. In public places, respecting others' rights and space is very important and should not be limited only to quiet carriages. Therefore, in addition to introducing quiet carriages,
education and promotion of passenger compliance with public order
and respect for others are equally important.

Overall,
the introduction of quiet
carriage is a positive move towards improving travel quality but at
the same time requires strengthening education
and supervision on politeness
and consideration for all carriage passengers.
