Immortal in Chinese / Japanese...

仙 means immortal (as in a being or person).

In some contexts, it can mean hermit, ascetic, man of the hills, or wizard. The Buddha is often put in this category.

In Chinese mythology and folklore, there is a famous group of eight immortals (八仙).

The 楞嚴經 (Śūraṅgama Sūtra) speaks of many kinds of immortals including walkers on the earth, fliers, wanderers at will (into space or into the deva heavens), beings with the ability to transform themselves into any form, etc.

不朽 means immortal or immortality in Chinese, Japanese Kanji, and old Korean Hanja.

The literal translation is “without decay” or “never rotting.” This title speaks of something or someone who never dies and thus never rots or decays.

This can also be translated as everlasting, eternal, or imperishable.

永生 are the last two words from John 3:16 in the Chinese Union Bible.

Although not specifically Christian, this is the way to express ever-lasting life or eternal life in Chinese.

In Japanese, this can either mean eternal life or immortality.

獲得永生的鑰匙是先要活得精彩 is a famous quote from Bruce Lee.

However, when quoted, he was speaking in English. So this is a translation of his English quote into Chinese. Since Bruce spoke both Chinese and English, his quotes sometimes go both ways.

壽 can be defined as “long life” or “longevity” in the simplest form.

Please note that Japanese use a simplified version of this character - it also happens to be the same simplification used in mainland China. Click on the character to the right if you want the Japanese/Simplified version.

Used as a noun, this word means “longevity” or “the ability to live long.”

It can also be an adjective meaning “long-lived.”

Please note that Japanese use a simplified version of the second character of longevity - it also happens to be the same simplification used in mainland China. Click on the character to the right if you want the Japanese/Simplified version of this two-character longevity calligraphy.

南山之壽 is a wish for long life for someone. The first part of this Japanese phrase is “Nan Zan,” which means “south mountain.” This mountain is one of the good wishes, good fortune, and prosperity. The title is often used as a salutation of good wishes.

The third Kanji is just a connector, and the last Kanji means long life or longevity.

I guess you could translate this phrase as “May your life be as long as Nan Zan is tall.”

福如東海壽比南山 is a phrase that means “May you have good fortune as great as the eastern oceans, and may your life last as long as the southern mountains.”

In ancient Chinese mythology, the eastern oceans and southern mountains are where God resides (basically it is the same as saying “heaven”). So it's like saying, “May your good fortune and life be as vast as the heavens.”

There is also a longer, 14-character version of this phrase. Also, this can be cut into two scrolls (with half the phrase on each side - great for hanging on either side of a doorway). Just let me know if you'd like a special version (there is an additional cost).

不气不愁活到白头 is a Chinese proverb that means “Without anger or worry, you will have a long life, until after all your hair is white.”

It more literally reads, “Don't get angry or worried [and you will] live [long] till [all your] hair [becomes] white.”
