Cigarette butts are often thrown upstairs.

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

1. Ask politely: First, ask this question in a polite and humorous way, such as "Dear neighbor, 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. Attention: point out the serious consequences that cigarette butts may bring, such as "cigarette butts may cause fires and endanger our lives and property. 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, property management companies are also required to take measures to ensure that cigarette butts are handled correctly. Only in this way can our living environment become safer and more comfortable. "

Pay attention to courtesy and respect when asking questions, which will make neighbors more willing to accept your opinions and solve problems together.
