I have watched this several times in my childhood. I don't quite remember the story, but i do remember that i laughed until my breath was gone. Specially because of that lady who was following the protagonists, and beating the sh*t out of them for some reasons that i don't remember . I am not exaggerating if i i said that i was crawling, shaking, and shedding tears because of laughing. Don't know if my feelings would stay the same if i watch this movie right now at this age.
And i also do remember the last few scenes of the village that was attacked by some kung fu masters or something that was tio funny too and a little bit scary for child as i do remember.
