It is said that after arriving on Dragon Tiger Mountain, Som Dot accepted two disciples, Wong Leng, an illiterate, but diligent disciple, and Lee Siem. Lee Siem later became known as Siem Yuen, which means capable of grasping the depth of Buddhism. And Wong Leng became known as Wong Do Yuen.
After some years, Som Dot sent his two disciples down the mountain to spread his art of Shaolin, which was divided into three orders. The first order taught the principle of 10 soft and one hard, and was taught only on the top of the mountain. The second order was half hard, half soft power. The third order was based on extremely forceful techniques. This is the reason the art is sometimes called a "three door or gate" art today.
In doing so, as they descended the mountain, Wong Do Yuen and Lee Siem Yuen, at the middle gate of the mountain accepted a student named Chu Long Bot. Hiding the kungfu of the first order, they taught Chu Long Bot only the second order kungfu of Som Dot. At that time, the first order kungfu of Som Dot was not taught.
After learning the art, Chu, having no knowledge of the first order kungfu, betrayed Wong and Lee and used only the Chu surname to pass on what was called Chu Gar Gao - Chu Family Creed. The name was later changed again to reflect "Chu Gar Praying Mantis".
Chu Long Bot later taught Chu An Nam, who taught Yang Sao and Lao Sui, who was a friend of Chu Kwei, who was the father of Chu Kwong Hua in contemporary times. This order of kungfu was originally taught only at the middle gate of the mountain.
Later, as Wong Do Yuen and Lee Siem Yuen went back down the mountain, at the lower gate, a praying mantis insect popped out in front of them. Wong, being the first to step off the mountain, proclaimed the mantis must be a sign from Heaven and to avoid further persecution of Som Dot's Shaolin teaching, the Shaolin art of three orders should simply be called Praying Mantis.
At the bottom of the mountain, a man named, Choy Tit Ngau, (Tieh / Tit = Iron / Ngau / Niu = Ox) pleaded with sincerity to learn their kungfu and the two of them taught him Som Dot's third order of kungfu based on extremely forceful techniques.
Not knowing what to call the art, Choy, having no knowledge of the first or second order of Som Dot, eventually did the same as the Chu Clan and called the art Tit Ngau, or Iron Ox. Later Chung Lo Ku learned from Choy and passed on this teaching as Chung Gar Gao in the East River region. This kungfu of the third order was taught at the bottom of the mountain.
In China, it is said each of Som Dot's three orders of Shaolin Kungfu has it's advantage and each is worthwhile to learn and study.
