Once a mermaid-like creature appeared in this lake. A witness told me last year that as he was tending the school's yaks by the lake,suddenly a huge sound came from the lake along with water spewed t0 4-5 meters high. This column of water moved slowly to the lakeside, not too far from him. At that moment, he saw under the water column a creature with upper body like that of a woman, long hair... The yaks were greatly stirred by the scene and scattered around in panic. The creature kept staring at him. When it dived into water, its long black hair could be seen floating on the surface of the water... Based on what I know about the witness, I believe he didn't lie to me.
