The Humble One in Chinese / Japanese...

謙遜 can also be translated as being modest, humble, or unpretentious.

Being humble is considering others to be as important as yourself. You are thoughtful of their needs and willing to be of service. You don't expect others or yourself to be perfect. You learn from your mistakes. When you do great things, humility reminds you to be thankful instead of boastful.

This Humility title is also used as one of the 8 key concepts of Tang Soo Do. Often romanized as “Kyum Son.”

Also sometimes used in Japanese to express humility with an essence of modesty.

千慮一得 means “1000 tries, one success,” or “[a] thousand tries [leads to] one success.”

This proverb is a humble way to express your success, ideas, or accomplishments. As if you are a fool who just got lucky in inventing or creating something.

Translations for this proverb include:
Even without any notable ability on my part, I may still get it right sometimes by good luck.
Even a fool may sometimes come up with a good idea.

Compare this to the English idiom, “Even a broken clock is right twice a day.”

虚実 is a Japanese word that means “falsehood [and] truth” or “fiction [and] fact.”

This concept is used in warfare, gameplay, and martial arts strategies. 虚実 can be a strategy of real and/or deceptive moves. This gets to some Sun Tzu Art of War stuff where in warfare a strategic move is either a real and serious move or it is a deceptive blow.

Let's explore each character in more depth:

虚 was originally written 虛 (there is a very subtle difference in the strokes at the bottom of the character) and means unpreparedness, falsehood, emptiness, void, abstract theory, empty or unoccupied, diffident or timid, false, humble or modest, virtual, or in vain.
In the Buddhist context, 虛 represents the Pali/Sanskrit word “śūnya,” meaning empty, vacant, unreal, unsubstantial, untrue, space, humble, or in vain.
In ancient Eastern/Chinese astronomy, 虛 represents the “Emptiness” constellation (one of the 28 mansions in the sky).

実 was originally 實 in Chinese (they currently write it as 实 in Simplified Chinese) with the meaning, truth, reality, sincerity, honesty, fidelity, and substance.
The Buddhist context is similar, adding real, true, honest, really, solid, definitely, sincere, solid, fixed, full, to fill, fruit, kernel, verily, in fact, the supreme fact, or ultimate reality to the definition.
