Wong contested the notion that Lee was fighting for the right to teach Caucasians as not all of his students were Chinese . Wong stated that he requested a public fight with Lee after Lee had issued an open challenge during a demonstration at a Chinatown theater in which he claimed to be able to defeat any martial artist in San Francisco . Wong stated it was after a mutual acquaintance delivered a note from Lee inviting him to fight that he showed up at Lee's school to challenge him . Martial artist David Chin reportedly wrote the original challenge, while Wong asked Chin to let him sign it . </P> <P> According to author Norman Borine, Wong tried to delay the match and asked for restrictions on techniques such as hitting the face, kicking the groin, and eye jabs, and that the two fought no holds barred after Lee turned down the request . </P>
