Bones in Chinese / Japanese...

骨 is Chinese, Japanese, and Korean for bone or bones.

If your name happens to be Bone or Bones, this is a cool character for a wall scroll to hang in your home or office.

不磕不碰骨頭不硬 is a Chinese proverb that literally translates as: Without being knocked around a bit, [one's] bones won't become hard.

Figuratively, this means: One can't become strong without first being tempered by “hard knocks.”

While true for everyone, this sounds like the “Iron Body” form of Kung Fu, where practitioners' bodies are beaten (and often bone fractured) in order to become stronger.
For the rest of us, this is just about how we can be tempered and build character through the hardships in our lives.

This is not a common title for a wall scroll in China.

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.

If you like or collect and maintain koi fish, 錦鯉 is the wall scroll for you.

Technically, this is a certain and revered species of “koi fish” in Japan, but it is the most normal selection for a wall scroll (more normal than the actual Kanji for “koi” or “fish” alone.

This literally means “brocade carp” or “embroidered carp.” This term is also used to mean the same thing in China (which is the origin of koi fish breeding and cultivation, several generations before they became popular in Japan).

For those of you that don't know, the Kanji for “koi” (which is pronounced “goi” in this entry) really means “carp.” If you want the word that means “koi fish,” it would just be the generic word for “carp fish.” That would include both colorful carp and the more mundane gray carp (the ones people eat if they don't mind lots of bones).
