When reading an account of some battles in China, I came across the Chinese word, 嚴整. As it turns out, 嚴整 is only used in military circles to describe neat, orderly, and well-disciplined troops. Perhaps this is actually closer to the meaning I was taught while in the U.S. Marines.

The first character literally means stern, serious, strict, or severe (it can also mean airtight or watertight.
The second character means exact, in good order, whole, complete, and orderly.
Together, these two characters multiply each other into a word that expresses the highest military level of discipline.

安定 is a word that means: quiet; settled; maintain; calm and orderly; stability; equilibrium.

整然 is orderly, systematic, well-organized, trim, neat, tidy, and accurate in Japanese Kanji and old Korean Hanja.

This would be understood but is not used in Chinese languages.

整 is a single Chinese character that can mean: in good order, whole, complete, entire, in order, orderly, to repair, to mend, to renovate, and/or to fix something or somebody.

This was added for a customer who wanted a single character that meant orderly. It's kind of unusual for a wall scroll.

My Korean Hanja dictionary defines it as orderly, neat, tidy, and/or whole.

Note: In Japanese, this Kanji is usually understood as a male given name Hitoshi (other Kanji can also be Hitoshi). It is used in combination with other Kanji or Hiragana to create words about orderliness. Unless your name is Hitoshi, this single character is best if your audience is Chinese.

厳守 is a Japanese word for strict observance; adherence; scrupulous compliance; or being orderly (often in a military way).

自律 means self-discipline and self-control.

It is doing what you really want to do rather than being tossed around by your feelings like a leaf in the wind. You act instead of reacting. You get things done in an orderly and efficient way. With self-discipline, you take charge of yourself.

Not sure if this one works for a Japanese audience.

紀律 is a Chinese and Korean word that conveys the idea of extreme self-control and perhaps self-sacrifice, and obedience.

This word matches the kind of “discipline” I was in the Marine Corps. There is also an additional idea of maintaining order or being orderly in your tasks.

This idea would also fit an athlete training for the Olympics who gives up many pleasures to stay focused on their training.
