Strong Heart in Chinese / Japanese...

yì zhì jiān qiáng

의지견강

This phrase 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 possess the element of "heart" in the lower portion of both characters (they also partially carry the meaning "with whole heart").

The last two characters mean "strong" or "staunch."

Chinese word order and grammar is 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.

부동심

不動心 is one of the five spirits of the warrior (budo), and is often used as a Japanese martial arts tenet.

Under that context, places such as the Budo Dojo define it this way: An unshakable mind and an immovable spirit is the state of fudoshin. It is courage and stability displayed both mentally and physically. Rather than indicating rigidity and inflexibility, fudoshin describes a condition that is not easily upset by internal thoughts or external forces. It is capable of receiving a strong attack while retaining composure and balance. It receives and yields lightly, grounds to the earth, and reflects aggression back to the source.

Other translations of this title include imperturbability, steadfastness, keeping a cool head in an emergency, or keeping one's calm (during a fight).

The first two Kanji alone mean immobility, firmness, fixed, steadfastness, motionless, idle.

The last Kanji means heart, mind, soul, or essence.

Together, these three Kanji create a title that is defined as "immovable mind" within the context of Japanese martial arts. However, in Chinese it would mean "motionless heart" and in Korean Hanja, "wafting heart" or "floating heart."
