IN a big lake at the top of the sacred Changbai mountain in Jilin province, a strange being rises from the ice-cold water, flashes its hulky body for just a few moments to tease a passer-by, then swims away into the distance at the speed of a motorboat.
No one has really seen the guaishou, or weird animal, up close, but everyone in this corner of the northeast has an opinion about China's version of the Loch Ness monster.
Scientists are intrigued, tourists keep their cameras ready for a potentially lucrative photo, and the local travel authorities are rubbing their hands with the prospect of a tourism bonanza.
Claims of monster sightings, from more than 100 people so far, are taken so seriously in Jilin that at the end of 1993 a Research Association for Queer Animals was set up. Among the 50 members are prominent journalists, television personalities, scientists and travel officials.
People cannot agree on exactly what the monster looks like, ''but it's definitely not a fish'', said Hou Wei, head of international marketing at the Yanbian Tourism Bureau and deputy chief of the association.
''I myself haven't seen it. Too bad,'' he sighed.
