One possible version:
Dear Editor,
A Lining-up Day has been set in Beijing and it helps people enjoy an easier and more harmonious life. This has set a good example for other cities. Nowadays, some people are unwilling to line up when they are doing their shopping or waiting for the bus, so I think it is necessary to establish a Lining-up Day to remind them. In this way, people will form the good habit of lining up voluntarily. I do hope that we will stick to this practice and popularize it until each day becomes a Lining-up Day. I’m sure it will make a big difference and our society will become more and more pleasant.
Yours,
Li Hua
