The Whole World at Peace in Chinese / Japanese...

This proverb can be translated as the whole world at peace, peace and prosperity, peaceful and tranquil, peace reigns over the land, times of peace, peace and tranquillity, peaceful world, or from the Greek, times of halcyon.

Sometimes (rarely) written as 天下泰平 (variant 3rd character).

啟盛世開太平 means “To bring flourishing peace and security to the world (our current era).”

It's a wish that a new door leading to peace and prosperity could be opened to mankind.

Character and word breakdown:
啟 to open; to start; to initiate; to enlighten or awaken.
盛世 a flourishing period; period of prosperity; a golden age.
開 to open; to start; to turn on.
太平 peace and security; peace and tranquility; peace; tranquility.
I don't like to do breakdowns like this, as the words altogether create their unique meaning (encompassed in the main title above).

世界平和 is the Japanese title for “world peace” or “peace of the world.”

世界和平 is the Chinese title for “world peace.”

四海升平 literally means “all four oceans at peace,” which is a way to express “world peace.”

寧靜而致遠 is five characters from a longer ten-character proverb composed by Zhuge Liang about 1800 years ago.

The proverb means “Your inner peace/tranquility/serenity will help you see or reach far (into the world).”

The last word means “far” but the deeper meaning is that you will surpass what you can currently see or understand. Perhaps even opening up vast knowledge and understanding of complex ideas.

安 is used in a lot of compound words in the CJK world.

Alone, this character has a broad span of possible meanings. These meanings include relaxed, quiet, rested, contented, calm, still, to pacify, peaceful, at peace, soothing, or soothed.

安 and even the pronunciation was borrowed from Chinese and absorbed into both Japanese Kanji and Korean Hanja. In all these languages, this character is pronounced like “an.”

淡泊以明志寧靜而致遠 is a kind of complex ten-character proverb composed by Zhuge Liang about 1800 years ago.

This is a Chinese proverb that means “Leading a simple life will yield a clear mind, and having inner peace will help you see far (into the world).”

What I have translated as “simple life” means NOT being materialistic and NOT competing in the rat race.

The last word means “far” but the deeper meaning is that you will surpass what you can currently see or understand. Perhaps even the idea of opening up vast knowledge and understanding of complex ideas.

The whole phrase has a theme that suggests if you are NOT an aggressive cut-throat person who fights his way to the top no matter how many people he crushes on the way, and instead seek inner peace, you will have a happier existence and be more likely to understand the meaning of life.
