Every year Chinese come by the tens of thousands, including skeptical scientists, to investigate the mysterious "Kanasi Huguai," communism's version of the Loch Ness monster.     2005 marks the 20th anniversary of the first sighting of this oriental creature. Communists have always been skeptical of psychic phenomena and cryptozoological creatures, dismissing them as superstition, an offense to communist dogma.     In today's Wal-Mart-fueled China, mythmaking and chasing are a big industry, and the supernatural and the paranormal are no longer taboo.     Reports of a Chinese "Bigfoot" have been repeated by the offical Xinhau News Agency, and UFO sightings are treated with great seriousness. A conference on the topic was held this year, and UFO believers claim support from famous scientists and and even cooperation with the ultra-secret Chinese army.     Chinese Mongolians known as the Tuwa people first began repoting about an ancient legend of the monsters in Kanasi in 1972. The creatures of the Tuwa stories were investigated some ten years later and were said to look like giant tadpoles with gaping mouth and huge eyes, a modern day dragon.
