Xin in Chinese / Japanese...

信 can mean to believe, truth, faith, fidelity, sincerity, trust, and confidence in Chinese, old Korean Hanja, and Japanese Kanji.

This single character is often part of other words with similar meanings.

It is one of the five basic tenets of Confucius.

In Chinese, it sometimes has the secondary meaning of a letter (as in the mail) depending on context but it will not be read that way when seen on a wall scroll.

In the Buddhist context, this is śraddhā (faith through hearing or being taught).

心 would often be translated as “heart.”

However, because it was believed in Chinese culture for thousands of years that your consciousness and thoughts came from the big red organ in the middle of your chest, it also means “mind” or “spirit” and sometimes even “soul.”

In Korean, beyond heart, mind, and spirit, this character can mean moral, nature, mind, affections, intentions, core, and center. In fact, it is used in Chinese to mean “center” as well but only with another character in front of it. For instance, “medical center” or even “shopping center.” Separately and alone, it will not be read with that “center” meaning unless thought of as “the center of your soul.”

信 is another character that expresses the idea of honesty.

It can also mean truth, faith, belief in, fidelity, sincerity, trust, and/or confidence.

Some have included this in the list for the Bushido, although “makoto” is probably more common/popular.

Note: In some contexts, this character can mean a letter (mail), news, or envoy. However, alone, it will generally be read with the honesty-meaning.

欣 is the type of happiness that you feel on the inside. It is the feeling of being released and delighted as well as being in a state of contentment. 欣 is more the internal happiness that perhaps only shows by the smile on your face. It can also be translated as “to take pleasure in” or “to rejoice.”

Note: 欣 is often used in compound words - especially in Korean Hanja.
As Japanese Kanji, this is so rare, that most Japanese people are not aware of its existence.
