A struggling teacher (John Cheung) is bullied, then dumped by his own kung fu students. Meanwhile, an odd man in a coolie hat comes to town, pretending to be a trade delegate for tea and salt. But he’s really the murderous Ah Yen (Bolo Yeung), who ten years ago wiped out many residents of Red Clay Village, and his favorite trick is to play the flute while kung fu fighting. The struggling teacher gains kung fu skills which include strokes based on writing, then he is the only one left standing to fight the Ah Yen. A classic of the genre! Also stars An-an Yu.
