勇敢 in Chinese / Japanese...

勇敢 is about courage or bravery in the face of fear.

You do the right thing even when it is hard or scary. When you are courageous, you don't give up. You try new things. You admit mistakes. This kind of courage is the willingness to take action in the face of danger and peril.

勇敢 can also be translated as braveness, valor, heroic, fearless, boldness, prowess, gallantry, audacity, daring, dauntless, and/or courage in Japanese, Chinese, and Korean. This version of bravery/courage can be an adjective or a noun. The first character means bravery and courage by itself. The second character means “daring” by itself. The second character emphasizes the meaning of the first but adds the idea that you are not afraid of taking a dare, and you are not afraid of danger.

勇敢 is more about brave behavior and not so much the mental state of being brave. You'd more likely use this to say, “He fought courageously in the battle,” rather than “He is very courageous.”

勇敢的心 is the title “Braveheart,” as in the movie starring Mel Gibson.

The character meanings break down this way:
勇敢 brave.
的 possessive particle.
心 heart/mind.

幸运眷顾勇敢的人 can be translated as “Fortune favors the brave/bold/courageous” in Chinese.
