Coarseness in Society

Coarseness is a widespread problem in modern society, which has a negative impact on our lives and social environment. From the food we eat to the language we use, from the music we listen to to the way we behave, coarseness can be seen everywhere. It has a negative impact on our mental health, social relationships, and even our physical health.

In order to improve the situation, we need to start from ourselves and make a conscious effort to avoid using coarse language and other behaviors that may make others feel uncomfortable or offended. We should also promote positive values and encourage people to adopt more polite and respectful behaviors, which will help create a more harmonious and civilized society. In addition, laws and regulations should be strengthened to protect the rights and interests of individuals and society as a whole, and harsh punishment should be imposed on those who intentionally cause harm to others.
