Lake Tianchi Monster
On September 6, 2007, Zhuo Yongsheng (director of a TV station's news center run by the administration office of the nature reserve at Mount Changbaishan, Jilin), shot a 20-minute video of 6 seal-like, finned "Lake Tianchi Monsters", near the border with the Democratic People's Republic of Korea (DPRK). He sent pictures of the Loch Ness Monster-type creatures to Xinhua's Jilin provincial bureau. One of them showed the creatures swimming in 3 pairs, in parallel. Another showed them together, leaving ripples on the volcanic lake.
