“不言実行" can be translated to "Actions
Speak Louder Than Words." This phrase conveys the idea that actions and results are more important than just talking about something. Instead of making promises to people, it's important to quietly work hard and achieve actual results. It's about demonstrating your commitment through your actions rather than just making big claims with words.
This concept highlights the significance of backing up your words with concrete efforts and outcomes, which is considered an important attitude among adults.
