Welfare in Chinese / Japanese...

民生 is the Chinese, Japanese Kanji, and old Korean Hanja for people’s livelihood, people’s welfare, or public welfare.

It is a product of benevolence for your fellow humans.

自他共栄 can be translated in a few different ways. Here are some possibilities:
Benefit mutually and prosper together.
Mutual welfare and benefit.
A learning concept of mutual benefit and welfare (that applies to all fields of society).
Mutual prosperity.

The first two characters are easy to explain. They are “self” and “others.” Together, these two characters create a word that means “mutual” (literally “me and them”).

The third character can have different meanings depending on context. Here, it means “in common” or “to share.”

The fourth character suggests the idea of “prosperity,” “flourishing,” or becoming “glorious.”

It should be noted that these Kanji are used almost exclusively in the context of Judo martial arts. 自他共榮 is not a common or recognized Japanese proverb outside of Judo.

You may see this romanized as Jita-Kyoei or Jitakyoei.

In modern Japanese Kanji, the last character looks like instead of . If you want the older/traditional version, please let us know when you place your order.

幸福 is a general state of happiness that can also be translated as truly blessed, welfare, well-being, or fortunate.

This is a nice word that means peaceful, tranquil, calm, composed, “free from worry,” “public peace,” tranquility, good health, well-being, or welfare in Chinese and Korean.

Note: The definition in Japanese is not so broad but still means peaceful or “public peace.”

永遠の幸福 means “eternal happiness” in Japanese.

永遠 means eternal, eternity, perpetuity, forever, immortality, and permanence.

の is a possessive article which sort of makes this selection mean “happiness, of the eternal kind.”

幸福 means happiness, though this word can be translated as truly blessed, joy, happy, welfare, well-being, or fortunate.

公安 is the Chinese, Japanese Kanji, and old Korean Hanja title for (The Ministry of) Public Security. 公安 can also generally mean public safety, public security, or public welfare. It is a positive term in Japan, where some even name their daughters “Kouan” (this title).

In China, this is the kinder name for the PSB or Public Security Bureau. It's really the national police of China - occasionally brutal and seldom properly-trained or educated. Once in a while, you find a PSB officer who lives up to the title of 公安. Before the 1989 massacre, it was the PSB officers who refused to stop nor kill any of the protesting college students (so they're not all bad). The Chinese government had to call in soldiers from Inner Mongolia to kill thousands of protesters.
