Cigarette butts are often thrown upstairs.

When the owners mentioned that cigarette butts are often thrown upstairs, you can express them in the following ways:

1. Politely put forward: First, put forward this question in a polite and humorous way, for example, "Dear neighbors, I have a little trouble. Recently, I found that there are always cigarette butts in our corridor. I know there may be a' heavy smoker' among us, but please note that this not only affects our environmental sanitation, but also may cause a fire. If this' heavy smoker' is you, then please consider changing your habits, or at least throwing cigarette butts in the right place. "

2. Pay attention: point out the serious consequences that cigarette butts may bring, for example, "cigarette butts may cause fires, which will endanger our lives and property safety. If we let this happen, then one day, our corridor will become an ashtray. "

3. Call for action: Finally, call for action: "Let's clean the corridor together and keep it clean and tidy. At the same time, the property management company is also requested to take measures to ensure that cigarette butts are handled correctly. Only in this way can our living environment become safer and more comfortable. "

When you ask questions, you should also pay attention to being polite and respectful, which will make your neighbors more willing to accept your opinions and solve problems together.
