英文說明:This type of drenching pipe is called a "gu-koan-tang" in Taiwanese. It was used to deliver medication in liquid form to ailing cattle. Most such implements were bamboo tubes, primarily made from either the Bambusa stenostachya Hackel or Dendrocalamus species. The tubes were around 8 or 9 cm in diameter, and were 30 to 50 cm long. The opening of the tube was slanted to allow the removal of the interior of the plant and the production of the tube shape. Medication was poured into the slanted end.
