The Chen clan or family was a small kingdom from 1046 BC to 479 BC. It was one of 12 small-but-powerful vassal states during the Spring and Autumn Period 770-475 BC. This name reappeared as the Chen Dynasty (陳朝) of the Southern dynasties from 557 AD to 589 AD.

金雞獨立 or “Jin Ji Du Li,” means “golden rooster stands on one leg.”

This is also called “crane stance” in English. This is used in wushu, karate, and other forms of martial arts.

This can be pronounced, “kinkei dokuritsu” in Japanese but it's rarely a title used in Japanese.

仁神術 is Jin Shin Jyutsu or Jin Shin Jutsu.

This is a practice of calming the mind and clearing the flow of Qi energy in the body. Jin Shin Jyutsu has some commonality with the practice of Reiki.

A good translation of 仁神術 would be “Benevolent Spirit Method.”

We can break that down into all of the possible meanings:

仁 = benevolence (esp. as a virtue of Confucianism), consideration, compassion, humanity, charity, kindness, or virtue.

神 = deity, soul, spirit, mysterious, psyche, god, divinity, spiritual powers, deva, divine, spiritual, or supernatural.

術 = way, method, means, art, trick, or plan. The correct romaji for this 術 Kanji should be “jutsu.” However, in martial arts, this is often written “jitsu” but in this case, “jyutsu” became common.
