The Mao Ying Kuen International Federation represents the Hei Ng Mun or Chi Wu Men (氣五門) family, which carries a unique southern gōngfu family lineage. Chi Wu Men is a traditional style based on the five animals fists, or five gates fist but has the main style centered on the cat fist. Mao Ying Kuen gōngfu (猫形拳), originated from Hubei province in southern China, and translates as "Cat Shaped Fist". The Mao Ying Kuen and the Hei Ng Mun are authentic and traditional gōngfu styles that have been recognized by many martial arts federations around the world.

There are many elements from Hung Kuen in Leung Wing-hang's Kung Fu style, which he has practiced for many decades. According to the book "Snake, Cat and Crane The combined fist," the patriarch Leung Wing-hang absorbed elements of the Dai Min Jeung "the big cotton palm" and the Ying Jaau Tong Long Bo Yin Sun " Southern eagle claw, mantis step, swallow body" to combine these techniques and develop the cat fist.

With no doubt, Leung Wing-hangs kung fu influenced many, not only for the legacy he left with the cat fist and his incredible knowledge in martial arts and medicine of traditional Dit-da traumatology, and also as a kung fu movie actor and director back in the '50s, but according to Hung Kuen Research Association, it is most likely that grandmaster Leung Wing-hang was also responsible to develop the Wudip Zoeng Tao Lu (蝴蝶掌) (Butterfly Palm Form), a secret Kung Fu technique from the Shaolin temple, which nowadays is part of many Hung Kuen schools curriculum.

Leung Wing-hang (梁永享) was a well-known traditional dit da doctor and kung fu teacher in Hong Kong from 1930-1974. Leung Wing-hang began his martial arts studies in Guan Zhou under So Hak-fu, one of the famed Ten Tigers of Canton. After his death, Leung Wing-hang was a disciple of Wong Fei-hung, the most renowned of the Ten Tigers. After training with Wong Fei-hung, Leung Wing-hang moved to Hong Kong and enrolled in one of Lam Sai-wing schools, beginning his training with him. At Lam's school, Leung studied the Southern Hung-Kuen style. Leung Wing-hang wrote a book on a style he created himself called the "Snake Cat Crane Combined Fist". The Snake Cat Crane Combined Fist, also known as the "Three Shapes Fist" or "Sam Yin Kuen", was created in the 1920s.

In his work travel through Hubei, he met several kung fu masters and exchanged martial arts knowledge and medical techniques with them. Two elderly guards, Yeung Han-git (楊漢傑) and Chan Saam-gaap (陳三甲) both became a great influence on the Leung development of the Sam Yin Kuen (三形拳) style. The Yeung's family martial arts style was Dai-min-jeung (大綿掌), and Chan's martial arts were called Ying-jaau-tong-long-bo-yin-sun (鷹爪螳螂步燕身). Observing and exchanging techniques with them, Leung was motivated to develop his style emphasizing softness.

From the five animal fists, Leung decided to extract the soft aspect of the snake and the crane. He also realized that the tiger and the leopard could be strong and fast at the same time, so he decided to combine both animals in one to develop the cat fist. After a long time of studying, he realized that the cat fist was a combination of the Wu Xing philosophy. The intention of Leung Wing-hang was never to replace the five animal styles with the cat fist, but to connect the cat with the five animals, and the five will become one. Leung concluded that his kung fu could reach the next level by combining the Snake, Cat, and Crane with the essence of Yung's and Chan's styles. After 1931 Leung returned to Honk Kong, to operate his Dit-da medical clinic and teach martial arts.

After World War II, when the Japanese occupied Hong Kong, many Kung Fu masters hid or moved from China to other countries. According to the history book "History Of Asian Americans: Exploring Diverse Roots" by Jonathan Lee, the majority of the Chinese population who moved from China to America, escaped to the United States, Brazil, Peru, and Venezuela. 

Pang Ming-hou (彭明浩) was born in 1908 in Chongqing province, he was a peasant, before moving to Hong Kong in 1942. His first experience with martial arts began when he was 6 years old when he practiced southern Shaolin with his uncle, and later his best friend taught him Hakka Kung fu as well. In 1942 Pang Ming-hou moved to Hong Kong, where he got a job first pulling a rickshaw a few years later he met a restaurant owner, who offered him a better job in a restaurant. According to the narrative, Pang met a Kung Fu master in this restaurant, according with Leung Wing-hang and after a conversation, Leung invited him to practice martial arts and helped him to refine his style. In 1961 because of Chinese communism, Pang Ming-hou moved to Brazil.

In São Paulo, he became a truck driver. Six years after, he met Ronald Candido Ferreira who was 13 years old. Ronaldo was born in 1953 in Sao Paulo. He started practicing Judo and Karate in 1963. While Ronaldo was practicing Karate in a park, he met Pang Ming-hou. After observing Ronaldo practice, Pang decided to invite him to play a martial arts game. After winning, Sifu Pang accepted Ronaldo as his student. 

After 4 years of training, Ronaldo finds out that Sifu Pang Ming-hao died due to an attempted robbery of one of the trucks he was driving. A year later he moved to Osasco - Sao Paulo, Brazil. Sifu Pang wrote a Chinese ideogram scroll to Ronaldo in one of his last training sessions, translated years later. The Chinese scroll was related to the southern cat fist, which nowadays is known as Mao Ying Kuen Gōngfu (猫形拳). 

Ronaldo kept training with his two brothers until they opened the Mao Nan Quan Martial Arts Academy on October 10th, 1977 in Sao Paulo Brazil. In 2022, Ronaldo after facing some health problems completely stopped teaching and he delivered a box with scrolls and a photograph of Pang Ming Hou to grandmaster Edvalson F. dos Santos who would be the successor of his lineage.   Nowadays, there are martial arts schools in Brazil, the United States, Mexico, and Italy, the schools associated with the federation that kept the traditional system, and some others not associated with dismembered the style completely.

Many Hung Kuen masters do not accept Leung Wing-hangs kung fu as part of hung Kuen's system, because the patriarch modified the essence, the tradition, and the elements from hung Kuen's gōngfu like the Hung Gar Sifu Marciel C. Rodrigues student of grandmaster Li Hon Ki-in Sao Paulo Brazil. According to Sifu Marciel C. Rodrigues: "The Hung Gar system should never be modified, Hung Kuen is a complete style, and emphasizing the cat rather than the tiger, would change completely the essence of the style. What Leung Wing-hang created or learned from someone else, was a different style completely separated from Hung Kuen, the form and the style are very beautiful and impressive and can be effective as well. Also, there is nothing wrong with creating a new style, but this is not Hung Kuen." On the other hand, some other masters liked the idea and the alteration and even adopted the Sam Yin Kuen as part of their curriculum. This included schools in Europe, the USA, and Brazil.

There are very few movies that give reference to the cat gōngfu style. It is arrogant to say those moves were made because of Leung Wing-hang's gōngfu style, but in some of the movements, there are some similarities which is a mere coincidence. Movies such as:


Lackey and the Lady Tiger


Snake in the Eagle's Shadow


8 Strikes of the Wild Cat


The Prodigal Son


cat vs rat


Revenge of the kung fu mao


kung fu master named drunken cat

Mao Chao CHuan - Magazine article


Magazine "Boxeo de la Garra del Gato" from 1986, is an article written by  Sifu David Conches and Sifu Pedro Izquierdo in Spain about the cat Kung Fu fist. In this article, Sifu Pedro Izquierdo who was a student of Wong Ping Pui, a former Hung Kuen Master, briefly talks about the Cat kung fu fist and the Sap Yin Kuen and Sam Yin Kuen movements applications in combat, which were passed down from his Sifu to him.

Sifu Pedro Izquierdo was part of the European Professional Karate and "Asociacion y arbitro auxiliar" EPKA and was also instructor at Hak Pao Kung Fu School in Barcelona, Spain. He practiced the Changquan, Hung Kuen and Maozhuaquan (猫爪拳) or Mao Chao Chuan styles. According to Sifu Izquierdo, there was a legend from five monks called "The Five Intercessors" back in the Qing Dynasty who developed the cat fist Kung Fu style in the Southern Shaolin temple. Years later was passed down to a Hung Kuen master called Hung Hei Kun. According to this article, the cat fist can be traced to the Hung Kuen system years before the Leung Wing-hangs age.

Sifu Izquierdo after studying for many years, in this article, compared the similarity of movements of Ying Jow Nim Kyu (southern eagle claw) from Bak Mei system also mentioned in Jackie Chan's cat and snake fist movie. Interestingly, the  Mao Ying Kuen style has those 3 fists in separate forms. In his point of view, the Mao Chao Chuan or Maozhuaquan should focus on strengthening the claws, to have a hard grip, fast like the leopard and deadly like the tiger. According to him, in the Sam Yin Kuen, many masters focus too much on Tiger Crane's application of fist and stance instead of translating the tiger fist to the cat essence.

The style also works deeply in studying the Lao Gong and its application on each point. The main areas to focus on are gentiles, throat, eyes, and face. Sifu Izquierdo also talks about a Tao Lu called the "Drunken Cat" which is called Zui Mao Chao.

"Un arbol puede ser muy grande y fuerte, pero si el viento lo azota fuerte y persistemente, este puede ser quebrado o arrancadas sus raices de la tierra, no asi el mimbre o el bambu, que al ser muy flexible es movido por la fuerza del viento, permaneciendo siempre con sus raices enchadas en la tierra." --- Sifu Pedro Izquierdo

Despite different perspectives about tradition, lineage, and martial arts, more important than the story itself, is what we learn from the historical evidence and the message that the "legend" or "tale" itself passes on. Regardless of any martial arts style, the resilience and humility of masters influenced and changed many lives due to their character, integrity, and history announced in different narratives, which were passed down to the students as a way of learning and served as inspiration.
