This literally translates as “the red string” or “the red thread” in Japanese, but the real meaning is much deeper...

In Japanese culture, it's believed that fate, destiny, or karma joins lovers by an unseen string, tied around one little finger of each. 赤い糸 is how soul mates find and are drawn to each other.

The Japanese concept of the red thread of fate, by most estimations, comes from Chinese folklore, where it's known as 姻緣紅線. The only difference is that in China, the celestial red thread is tied around the ankles of the lovers (versus what is usually represented as the pinky finger in Japan).

提携 varies a bit depending on which language you are reading it in.

提携 means to guide and help (younger people) in Chinese.
Cooperation or “working in concert” in Korean.
And cooperation, tie-up, joint business, and link-up in Japanese.

鐵拳 is a common theme used by various schools of martial arts.

鐵 means “iron” but, in some cases, can mean “indisputable.”
拳 means fist.

Some schools use the older/Taiwanese way to Romanize the iron fist, so you may have seen it spelled “Tieh Chuan” instead of “Tie Quan.” Neither way is technically incorrect.

Note that in Mandarin, the first part of the first character sounds like the English word “tea,” blending into a soft “-eh” sound. The second character sounds a lot like “chew on” but as if it is one syllable.

After WWII in Japan, the Kanji for iron was simplified. This new Kanji form is shown to the right. If you want this modern Japanese version, please click on the Kanji to the right, instead of the button above. The characters shown to the left would still be considered the old or ancient Japanese version of this title.

太極拳 is the famous Taoist meditation and martial art exercise. The direct translation of these characters would be something like “grand ultimate fist,” but that does not quite hit the mark for what this title really means.

An early-morning walk through any city in China near a park or an open area will yield a view of Chinese people practicing this ancient technique.

A typical scene is an old man of no less than 80 years on this earth, with a wispy white beard and perhaps a sword in one hand. He makes slow moves that are impossibly smooth. He is steady-footed and always in balance. For him, time is meaningless and proper form, and technique is far more important than speed.

For the younger generation, faster moves may look impressive and seem smooth to the casual observer. But more discipline and mental strength are needed to create perfectly smooth moves in virtual slow motion.

Note: There are two ways to Romanize these Chinese characters, as seen in the title above. The pronunciation and actual characters are the same in Chinese. If you really used English sounds/words to pronounce this, it would be something like “tie jee chew-on” (make the “chew-on” one flowing syllable).

鐵匠 means blacksmith or ironworker in Chinese.

鐵 means iron or tough metal.

匠 means craftsman or artisan. 匠 can also mean carpenter (in the context of woodworking rather than metal forging).

體貼 is a Chinese word that means to be considerate (of other people's needs).

鐵心 can be translated as “iron heart,” “steel core,” or “iron mind” in Chinese and Japanese Kanji.

This is not a common term, but I added it here since so many were looking for “iron heart.” This is almost like saying you are without emotions or feelings - a very stoic person. This is not a Buddhist trait.

鐵掌 means “iron palm,” the martial arts technique taught by Brian Gray and others.

This term can mean different things to different people. The consensus is that rather than a type or style of martial arts, this is a technique for refining hand position and strengthening hands to strike blows with maximum force and effect.

The regime may include herbal treatments and special exercises to fortify the hands.

In more extreme versions, the carpals and metacarpal bones in the hand are systematically broken so that when they heal, they will become stronger.

Japanese note: This does make sense in Japanese (though the version shown above is the ancient form of the first Kanji), this is far from a commonly-known term.

鐵龍 is the title Iron Dragon in Chinese.

鐵人 is the Chinese name for the Ironman Triathlon Event.

The literal meaning of these characters is “iron person.”

This can also refer to a Japanese toy, Tetsujin (a big blue tin man).

In ancient China, 饕餮 was a ferocious mythological animal and the fifth son of the dragon king.

饕餮 can also refer to a zoomorphic mask motif found on Shang and Zhou ritual bronzes.

As an adjective, this can mean gluttonous, sumptuous (banquet), covetousness, greed, avarice, or intense desire.

以斯帖 is the name Esther in Chinese (Mandarin).

鋼鐵俠 is the Chinese title for Iron Man, the comic book superhero.

鐵了心 is a Chinese title that means determined or unshakable.

This literally means “Iron Heart” or “Heart of Iron.”

體貼入微 is a Chinese idiom that means “to show every possible consideration.”

This can also mean “meticulous care of others.”

古鐵雷斯 is the name Gutiérrez in Chinese (Mandarin).
