Title: The Uncivilized Act of Spitting in Public

In the streets and public restrooms, we can frequently find the marks of sputum. These are from some people's casual spitting. Not only do they spit casually in the streets, but they also do so in places like changing rooms, offices, or meeting rooms. They seem to be unbound by any rules or concerned about breaking social etiquette.

However, spitting in public is an uncivilized and immoral act. It is also a sign of ignorance and backwardness. Moreover, spitting can damage public health and spread pathogens of infectious diseases, thereby endangering the health of others.

In real life, many people are not aware that spitting can bring harm to society. Therefore, the phenomenon of spitting everywhere is not surprising: streets, schools, shops, stations, workplaces, and other places can all be seen with its traces. Do not underestimate this seemingly insignificant act； in fact, it contains countless germs and viruses. Under a high-power microscope, various germs and viruses can be seen in the sputum.

In order to protect our health and maintain social order, please do not spit casually. We should respect public places and others' health, and abide by social morals and laws. Only in this way can we create a civilized, healthy, and harmonious society.
