No Fighting in Chinese / Japanese...

百折不撓 is a Chinese proverb that means “Be undaunted in the face of repeated setbacks.”

More directly translated, it reads, “[Overcome] a hundred setbacks, without flinching.” 百折不撓 is of Chinese origin but is commonly used in Japanese and somewhat in Korean (same characters, different pronunciation).

This proverb comes from a long, and occasionally tragic story of a man that lived sometime around 25-220 AD. His name was Qiao Xuan, and he never stooped to flattery but remained an upright person at all times. He fought to expose the corruption of higher-level government officials at great risk to himself.

Then when he was at a higher level in the Imperial Court, bandits were regularly capturing hostages and demanding ransoms. But when his own son was captured, he was so focused on his duty to the Emperor and the common good that he sent a platoon of soldiers to raid the bandits' hideout, and stop them once and for all even at the risk of his own son's life. While all of the bandits were arrested in the raid, they killed Qiao Xuan's son at first sight of the raiding soldiers.

Near the end of his career, a new Emperor came to power, and Qiao Xuan reported to him that one of his ministers was bullying the people and extorting money from them. The new Emperor refused to listen to Qiao Xuan and even promoted the corrupt Minister. Qiao Xuan was so disgusted that in protest, he resigned from his post as minister (something almost never done) and left for his home village.

His tombstone reads “Bai Zhe Bu Nao” which is now a proverb used in Chinese culture to describe a person of strong will who puts up stubborn resistance against great odds.

My Chinese-English dictionary defines these 4 characters as “keep on fighting despite all setbacks,” “be undaunted by repeated setbacks,” and “be indomitable.”

Our translator says it can mean “never give up” in modern Chinese.

Although the first two characters are translated correctly as “repeated setbacks,” the literal meaning is “100 setbacks” or “a rope that breaks 100 times.” The last two characters can mean “do not yield” or “do not give up.”
Most Chinese, Japanese, and Korean people will not take this absolutely literal meaning but will instead understand it as the title suggests above. If you want a single big word definition, it would be indefatigability, indomitableness, persistence, or unyielding.

国家忠诚父母孝道朋友有信杀生有择临战无退 are the five codes of Tang Soo Do.

I suggest you have this arranged in five columns when you get to the options page for your custom calligraphy wall scroll.

Here are my translations of each of the five codes:
國家忠誠 Be loyal to your country.
父母孝道 In regards to parents, behave in a filial way.
朋友有信 Be faithful in friendship.
殺生有擇 When fighting for life and death, make noble choices.
臨戰無退 No retreat in battle.

Note: “Tang Soo Do” is a romanization of 唐手道. It's 당수도 in Korean Hangul. It can also be romanized as “Tangsudo” or “Dangsudo.”

影武者 is the title for Shadow Warrior in Chinese and Japanese.

This may refer to a few video games that share this English title, or a Japanese movie called Kagemusha.

If you are looking for the Japanese TV show, that was originally 影の軍団 (Kage no Gundan), which more literally means “Army of Shadows,” but was re-titled Shadow Warrior when released outside Japan in English.

In Japan, this title can also refer to a body double or decoy of an army general or leader used to avoid assassination. It can also be somebody who does all the work (or fighting) behind the scenes (not getting much, if any, credit).
