Mantis108: During the time, Ching Wu schools were very sucessful and it was one of the highest honor to teach inthe Ching Wu schools. Living in China with many of its people were poor and starving and with other countries invading its land, it was difficult to establish their own school. Many sifus felt their style’s survival was in danger of disappearing in one generation. They realized that they needed to re-think and be more open minded.
To the best of my knowledge this is the order that Ching Wu teaches the sets. I have either learned or observed all of these sets except for number 9. I have yet to observe or locate any written document on this set.

These is only one weapon that has its roots associated with Tai Chi Praying Mantis, that is, the Nine Ring Saber. The saber set, Testing the Blade, is a very unusual saber set and is unlike other CMA saber sets (meaning techniques of one person verses many). This set consist of many strings of battle proven individual saber techniques (one against one) strung together. The original concept surrounding this set is that it was designed to trained the foot soldiers in quick fighting techniques. It is well known that Chui Chuk Kai borrowed many weapons from Tai Jo Men and this might be the original source of the set.

Sun Yu Fung did not teach Testing the Blade but did teach five other sabers.
Pa Kua Saber or Eight Trigam Saber (required by Ching Wu):Foot Solider Saber, Plum Blossom Saber, Split Door Saber (Sparring Sabers), Loose Wrist Saber (Sparring Sabers). Sometimes he would teach two additional sets: Swallow Pierces the Clouds and Snow Flakes.

As to your question about exchanging of sons to teach with Lum Yui Kwai, I do not have any info. However it was a common practice between GM’s to do this out of respect for each other. Later Sun’s son, Wen Yung, joined the army and became the General Martial Arts training Officer. He was killed in battle between 1934 and 35, when the Nationalist made the big push northward. This effected SYF to a point of deep depression and he quit teaching at the Ching Wu Association. He went to his teach with his top disciple’s school, Hwang Hsiao Hsia (His nickname is Iron Forearms, Yin and Yang Hands).

Beiquan: More on Wan Li Sheng
Wan Li Sheng and Kuo Yu Chang were very close friends. At the 1928 First National Tournament, the contests were ferocious and bloody. Wan Li Sheng had beaten all of his opponents and was in the semi-finals. In his last contest, Wan Li Sheng fought a White Crane opponent. Wan Li Sheng struck and broke his opponent's jaw. However, to Wan Li Sheng's disappointment, he also injured his hand and reluctantly dropped out of the tournament His hand received major cuts from his opponent's teeth when he struck his jaw. Wan Li Sheng ended up placing number forty eight (48). As the number of contestants got smaller, the fights became even more violent and brutal. Many of the contestants were taken away on stretchers with broken bones and other injuries. The government stopped the tournament when there were only thirteen contestants left. The audience was angry because they wanted to have one single champion of all China. The government officials announced to the audience that if the fights continued, many of the results would end in death because of the high degree of skill among the contestants that were left. The thirteen champions of all China were declared and the tournament was over. Among the thirteen champions were Kuo Yu Chaing of Northern Shao lin style, Fu Chen Sung of Pa Ku style, Li Hsin Wu of Northern Shao lin and Tan T'ui styles, Keng Te Hai of Monkey Style, Ma Cheng Hsin of Seven Star Praying Mantis style, Wang Shao Chou of Northern Shao Lin and Cha styles, Chu Kuo Chen, Chu Kuo Fu, Chu Kuo Lu, etc. Out of the thirteen champions, Wan Li Sheng felt that he was better than twelve of the champions. Wan Li Sheng decided to test the other twelve champions. He traveled to their home province and fought each one in their home schools. He believed that they were not that good and therefore did not deserve the title of Champion of All China. He believed that only Kuo Yu Chiang deserved the title. Wan Li Sheng challenged many of the champions and won. Wan Li Sheng felt that the populace were ignorant of true martial arts and were easily fooled by fake masters. Wan Li Sheng wanted to expose them and continued to challenge masters across the country. Soon everyone was familiar with Wan Li Sheng's reputation. Either the people hated him because of his attitude and arrogance’s towards the many masters that he fought or they loved him because he exposed the fake masters.
Once, Wan Li Sheng went to the Yang Family to try the famous Yang's Style of Tai Chi. Chang Ch'ing Ling, who was trained by Yang Pan Hou, came forward to meet the challenger. Yang Pan Hou was one of the sons of Yang Lu Ch'an, the founder of Yang Style Tai Chi. Chang Ch'ing Ling was a classmate of the famous Yang Ch'eng Fu , who was the grandson of Yang Lu Ch'an. It was said that Chang Ch'ing Ling could "root" his feet so well that they sank into the ground. As Chang Ch'ing Ling and Wan Li Sheng fought, observers noticed that both men were of equal abilities. The fight ended in a draw because both men injured their hands. Wan Li Sheng went as far as to challenge the famous Yang Ch'eng Fu. In this challenge, they both agreed to use Tai Chi pushing hand techniques. To Yang Ch'eng Fu surprise, Wan Li Sheng pushed him up into the air. Yang Ch'eng Fu at this time weigh three hundred (300) pounds. To many martial artists, this was real proof of how strong and how good Wan Li Sheng really was. Up to that time, no one had ever uprooted Yang Ch'eng Fu and more impressive because Wan Li Sheng had beaten a renown master using his opponent's own technique.
After the 1928 First National Tournament, the Kuo Ming Tung, under General Chang Chih Chang, appointed five (5) masters who became known as the Five Tigers From The North. These masters were Kuo Yu Chiang, Wan Li Sheng, Fu Chen Sung, Wang Shao Chou and Li Hsin Wu. Also included were three (3) well known masters who were Keng Te Hai, an expert in Tai Shan Style or monkey Style, Tung Yin Chieh, who was a Tai Chi master, and Sun Yu Fung. The Kuo Ming Tung requested the Ching Wu Cultural Association to send four (4) representatives: Chen Tzu Sheng of Northern Shao Lin Eagle Claw style, Lo Kwang Yu of Northern Praying Mantis (Seven Star), Keng Cha Kuan of Hsing I internal style, and Wu Chien Chuan of Wu style Tai Chi. Together they were ordered to discuss and develop the best techniques of each style and to put aside their prejudices of different styles. As a result they developed a diverse style called Long Fist which became very popular. The Five Tigers From The North were ordered by the Kuo Ming Tung to go south to Canton. They were ordered to meet with southern masters to form martial art schools and combine their styles together to form new and effective techniques. General Li Chao and six (6) southern masters were to form a new Kuo Ming Tung Association in Canton. The six (6) southern masters were Lin Yin Tang of Mo Gar style, Tam San of Ts'ai Li Fut style, Lin Yao Kuei of Dragon style, Chang Li Chuan of White Eye Brow style, Lin Shih Jung of Hung Gar style and Wu Chien Chuan of White Crane style. As a result, many new styles developed. Of these "new" styles, the most popular was North Wind Ts'ai Li Fut.
The defeat of the twelve (12) champions of the 1928 tournament by Wan Li Sheng was recognized by the Kuo Ming Tung. They appointed Wan Li Sheng as director of the Kwangsi Province school and gave him the rank of Major General. Many masters
became jealous of Wan Li Sheng's accomplishment and of his young age of thirty five (35). As a result many southern masters challenged Wan Li Sheng but each one fell before the superior skills of Wan Li Sheng. Many of the defeated masters acknowledged Wan Li Sheng's skills and described his abilities: " Wan Li Sheng's hands moved like ropes and his fingers were like iron hooks. He rushes forward like a hurricane and backed away like a torrential waters." Wherever he went, he was always surrounded by admiring followers who came from various parts of the country to learn from him. By 1930, Wan Li Sheng was very famous and many people regarded him as the symbol of Chinese Martial Arts. Since martial arts and Wan Li Sheng's fame did not "bloom" until after the 1928 National Tournament, many people call Wan Li Sheng the "Flower of the National Arts".
The Chief Army Officer was Li Chi Shen and he appointed Wan Li Sheng, who was a graduate from Peking University, to be head of both National Arts Provinces school in Kwangsi and Kwangtung and Kuo Yu Chang to be in charge of Kwangtung Province. WLS instructed everyone to assist Wang Shao Chou in developing a standard curriculum and they all decided to use the set, Lien Bo, from Wu Chih Ch’ing as the basic set. While KYU was there, he met Ch’ien Chan Sheng who taught him Ch’a style.
