Dre Parker: Mr. Han... Do you know you got a car in your living room?
Trivia: Ralph Macchio refused to make cameo appearance in this movie.
Question: Why did Cheng present the trophy to Dre and why did they all bow to Mr. Han?
Answer: Because Dre has finally earned Chengs respect. The other Fighting Dragons bowed to Mr. Han because in China bowing is shown as a sign of respect as they see that he is a better teacher and a kinder master then Master Li.
Since this movie mirrors the 1984 original movie, this is like how Johnny Lawrence (William Zabka) and the Cobra Kai's (excluding Dutch [Chad McQueen]) finally respect Daniel Larusso (Ralph Macchio), after the latter defeats Lawrence-The only difference is that the Cobras do not bow to Mr. Miyagi.
