The so-called "three parasites" refer to the long worm (Ascaris lumbricoides), the red worm, and the pinworm. The three parasites are also included in the category of the nine worms. The long worm is Ascaris lumbricoides, measuring about one chi in length. When it moves, it causes vomiting of clear fluid; when numerous, it leads to emaciation.
