Lee dropped out of college in early 1964 and moved to Oakland to live with James Yimm Lee. James Lee was twenty years senior to Bruce Lee and a well-known Chinese martial artist in the area. Together, they founded the second Jun Fan martial arts studio in Oakland. James Lee was also responsible for introducing Bruce Lee to Ed Parker, an American martial artist. At the invitation of Parker, Lee appeared in the 1964 Long Beach International Karate Championships and performed repetitions of two-finger push-ups (using the thumb and the index finger of one hand) with feet at approximately shoulder-width apart. In the same Long Beach event he also performed the "one inch punch." Lee stood upright, his right foot forward with knees bent slightly, in front of a standing, stationary partner. Lee's right arm was partly extended and his right fist approximately away from the partner's chest. Without retracting his right arm, Lee then forcibly delivered the punch to volunteer Bob Baker while largely maintaining his posture, sending Baker backwards and falling into a chair said to be placed behind Baker to prevent injury, though Baker's momentum soon caused him to fall to the floor. Baker recalled, "I told Bruce not to do this type of demonstration again. When he punched me that last time, I had to stay home from work because the pain in my chest was unbearable". It was at the 1964 championships that Lee first met Taekwondo master Jhoon Goo Rhee. The two developed a friendship—a relationship from which they benefited as martial artists. Rhee taught Lee the side kick in detail, and Lee taught Rhee the "non-telegraphic" punch. Rhee learned what he calls the "accupunch" from Lee and incorporated it into American taekwondo. The "accupunch" is a rapid fast punch that is very difficult to block, based on human reaction time—"the idea is to finish the execution of the punch before the opponent can complete the brain-to-wrist communication."
