In order to screen the best practitioners for teaching positions at the newly founded Central Guoshu Institute, and in the provincial schools, Generals Zhang Zhi Jiang (张之江) (1882–1966), Li Liejun (1882–1946) and Li Jinglin (1885–1931) held the first modern full contact, national competition in October 1928. Many traditional masters did not compete because they believed their skills could only be proven in serious duels and not "sporting" contests. However, the event attracted hundreds of the best Chinese martial artists who participated in boxing, weapons and wrestling in a lei tai ring format. But after the first several days, the fighting competitions had to be halted because two masters were killed and many more seriously injured. The final 12 contestants were not permitted to continue for fear of killing off some of the greatest masters of the time. The overall winner was voted on by a jury of his peers. Many of the "Top 15" finishers (some being Xingyi boxers) went on to teach at the institute.
