意志 in Chinese / Japanese...

意志 is a Chinese, Korean, and Japanese word that means “determination to achieve.” It can also be translated as: will; willpower; determination; volition; intention; or intent.

In Japanese, this can also be the given name, Ishi.

意志力 is a form of willpower or self-control and is about having the determination or tenacity to keep going.

In Japanese, this is the power of will, the strength of will, volition, intention, intent, or determination.

自由意志 is a concept that has existed for thousands of years that humans can understand right and wrong, then make a decision one way or the other (thus affecting their fate).

Sources such as Confucius, Buddhist scriptures, the Qur'an, and the Bible all address this idea.

As for the characters shown here, the first two mean free, freedom, or liberty. The last two mean “will.”

Can be romanized from Japanese as jiyū-ishi, jiyuu-ishi, and sometimes jiyuu-ishii.
It's 자유의지 or jayuu-yiji in Korean and zìyóu yìzhì in Chinese.

意志堅強 can mean either “strong-hearted,” “strong-willed” or “determination.”

The first two characters can be translated as “will,” “willpower,” “determination,” “volition,” “intention,” or “intent.” But, it should be noted that this first part possesses the element of “heart” in the lower portion of both characters (they also partially carry the meaning “with the whole heart”).

The last two characters mean “strong” or “staunch.”

Chinese word order and grammar are a bit different than English, so in this case, they are in reverse order of English but have the correct meaning in a natural form.
