What is the meaning of Enter the Dragon ? Why it was used .?

You know there was a dispute on the title of the film Enter the Dragon (龍爭虎鬥). At one time, the title was Blood and Steel and Bruce Lee insisted the name should be Enter the Dragon.
The drgaon stands for Bruce Lee. You know 李小龍 is not Bruce's real name. Bruce was born in the year of Drgaon, so he called himself the little dragon (小龍).
Back to the reason why the film was titled Enter the Dragon. The drgaon stands for Bruce Lee and the word enter means "hear comes" So the tile Enter the Dragon means Here comes the Dragon.
