Doctor in Chinese / Japanese...

醫生 is the title used to refer to medical doctors or physicians in China.

Note: Sometimes, this same term is used in Korean, but not common.

The meaning is close to “healer [of] life” as the first character, 醫, can mean medicine, the healing art, healing, curing, medical, to cure, or to treat. The second character, 生, means birth or life.

In Japan, they use a simplified version of the first character (医生 is also used as the Simplified Chinese version of Doctor). If you want this version, please click the characters to the right instead of the button above.

針療法 is one of two ways to write acupuncture in Chinese and Japanese.

The first character means “needle” or “pin.” The second character means “to treat” or “to cure.” The last character means “method” or “way.”

This is the only reasonable selection if your audience is Japanese. This is the formal way to express acupuncture in Chinese, so this version is universal in most of Asia (the best all-around choice in most cases).

針術 is a way to write acupuncture in Chinese.

The first character means “needle” or “pin.”
The second character means “technique” or “method.”

This is theoretically a Japanese word as well but not commonly used.

鍼灸 is the Chinese, Japanese Kanji, and old Korean Hanja word for acupuncture-moxibustion.

百胜难虑敌三折乃良医 is a Chinese proverb that literally translates as: [Even a general who has won a] hundred victories [may be] hard put to see through the enemy's [strategy], [but one who has] broken [his] arm three [times] [will] be a good doctor.

Figuratively, this means: One cannot always depend on past successes to guarantee future success but one can always learn from lessons drawn from failure.
