"空の器は一番大きな音を立てる。"

Simplified Meaning:

Imagine a person who talks a lot but doesn't have much to say. They might speak loudly or interrupt others, but their words don't carry much weight or valuable information. This idea can be compared to an empty container that makes a loud noise when struck because there's nothing inside to absorb the sound. In life, people who are truly knowledgeable or wise often don't feel the need to boast or show off. Instead, they listen more and speak thoughtfully. For example, in a classroom, a student who constantly talks during discussions might seem like they know a lot. However, their constant chatter often reveals they're not actually paying attention or understanding deeply. Meanwhile, a quieter student might share fewer comments, but when they do, their words often have more insight and meaning. To apply this idea in daily life, focus on being thoughtful and considerate with your words. Listen more, speak less, and make sure what you say is meaningful. This way, your voice and opinions will be valued more when you do speak up.
