Tang in Chinese / Japanese...

唐手道 is the alternate title for Karate-do.

This title uses a character, 唐, which represents the Tang Dynasty of China. Thus, this is often translated as the “Tang Hand Way” or incorrectly, “Tang Fist Way.”
I have also seen some call it “China Hand Way.”
Many in Korea refer to and romanize these characters as “Tang Soo Do” (당수도) where these characters refer to a kind of Korean style of Karate.

There is not a lot of information on this title but some believe that a simplified form of Kung Fu that started in China and ended up very popular in Japan used this title initially. It was later changed in Japan to a different Karate title which means “Empty Hand” (as in, without weapons).

Note: When used in Korean, this is pronounced 당수도. This title is often romanized as “Tang Soo Do,” “Tangsudo,” “Dang Su Do,” or “Dangsudo.” The last two romanizations on that list are the official Korean government romanization, though martial arts schools tend to use other non-standard versions.

廉耻精進忍耐遵守克己謙遜百折不屈 are the tenets of Tang Soo Do.

After some research, it appears this list was compiled in English based on Taekwondo tenets. We filled in a few of the words that did not have a corresponding Hanja or Hangul. If someone else has a better list with characters included, please contact me.

唐手 is a very seldom-used title for Karate.

This title uses a character that represents the Tang Dynasty of China. Thus, this is often translated as the “Tang Hand” or, incorrectly, “Tang Fist.”

I have also seen some call it “China Hand.”

There is not a lot of information on this title but some believe that a simplified form of Kung Fu that started in China, and ended up very popular in Japan used this title initially. It was later changed in Japan to a different Karate title which means "Empty Hand" (as in, without weapons).

I am sure that some will suggest a different history or argue a different origin. I think that nobody can be sure.

Note: Just like the more conventional Karate title, this one can have the "way" or "method" character added to the end, as in Karate-Do.

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.”
