Names and legends
In ancient Chinese literature, Tianchi also refers to Nanming (南冥 sometimes translated as "southern sea").
North Korean propaganda claims that Kim Jong-il was born near the lake on the mountain. In accordance with this, North Korean news agencies reported that on his death, the ice on the lake cracked "so loud, it seemed to shake the heavens and the Earth".
As part of the Korean summit, the heads of states Kim Jong-un and Moon Jae-in visited Mount Paektu and Heaven Lake on 20 September 2018. Moon filled a bottle with some water from the lake to take back to South Korea. The mountain and the lake have high cultural significance across the Korean peninsula.
Lake Tianchi Monster
Heaven Lake is also alleged to be home to the 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 six 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 three pairs, in parallel. Another showed them together, leaving ripples on the volcanic lake.
