Bệnh từ miệng vào, họa từ miệng ra.

Words have great power, and they can lead to both positive and negative outcomes. The saying "Illness enters by the mouth, trouble exits by the mouth" highlights this idea. Just as what we eat can affect our physical health, what we say can impact our lives and relationships. Careless or harmful speech can cause misunderstandings, conflicts, and even long-term damage to our reputation. On the other hand, thoughtful and kind words can build trust and strengthen bonds. This proverb serves as a reminder to be mindful of both our words and actions, as they shape our experiences and the world around us.
