The Karate Kid Part II (1986)

Continuity mistake: When Sato goes to see Miyagi, but he isn't there, Chozen destroys the dojo then tells his two friends to let Daniel go, and they throw him forward. His hands are not in the fighting stance, yet in the following shot he is now in his fighting stance with his hands at the ready. (01:15:25)

Chozen: Your teacher need a hearing aid. Maybe you need one too.
Daniel: I only hear what's worth listening to.

Trivia: When Daniel and Miyagi are picked up at the airport by Chosen, the radio is switched a few times before landing on a specific station. The song the radio is playing is the same song played at the country club in Karate Kid I where Johnny kisses Ali.

Question: When Chozen, while bullying Daniel, takes the latter's handheld drum (which Chozen mockingly called a "baby rattle") and calls the latter a baby, Kumiko, sticking up for Daniel, fiercely says a phrase in Japanese (or Ryukyuan) to Chozen. What exactly does Kumiko say, and what does it mean? (00:57:50)
