Dear Editor,

I am writing to suggest the establishment of a "Queuing Day" in our country.

In recent years, we have seen increasing numbers of people who do not queue properly, whether it is at supermarkets, train stations, or other public places. This not only leads to inefficiency and frustration but also undermines the social order and harmony. Therefore, I believe that a designated Queuing Day would be a step in the right direction.

The Queuing Day in Beijing has been a great success, as it has helped people enjoy a more relaxed and harmonious life. By setting a specific day for queuing, we can remind others of the importance of this habit and encourage them to follow it. If we could implement this in other cities as well, I am confident that it would lead to a significant improvement in social behavior and overall quality of life.

To make this a reality, I suggest that schools, workplaces, and public transportation should all participate actively. Schools can organize queuing drills during the school day, while workplaces can promote the practice during lunch breaks or work hours. Public transportation can also display signs and announcements to remind passengers to queue.

In conclusion, I urge you to consider my suggestion and support the establishment of a Queuing Day in our country. Let us all work together to cultivate good habits and make our society a more orderly and pleasant place to live in.

Sincerely,

[Your Name]
