Your know how to explain the term ¦Ê§é¤£¼¸? I told my kindergarden teacher in HK back in 1970's that everytime the Coyote failed to catch Road Runner, the Coyote will use another method to catch Road Runner again, never give up. Of course the teacher was not satisified. I believe the teacher in HK did not have that level of humor. If I did the same thing in USA, the teacher would be happy.
