The informant learned the following legend while studying abroad in Taiwan, and told it to me while recounting her experience at National Taiwan University.
“At National Taiwan University, there’s a big lake in the middle of campus, and it’s called Drunken Moon Lake, and the story is that there was a woman who was I think rejected by her lover, for some reason couldn’t be with her lover, and she drowned herself in the lake and I’m not sure how long ago it was, so they believe that a ghost is an unhappy spirit, like an unrestful soul. And they believe that she lives there on the lake. So there is a pagoda in the middle of the lake that doesn’t have a bridge to it, there’s no way to get to it, so there’s just birds there, and they believe that she lives there with other unhappy female ghosts, female sprits, and that if you’re a man, you should not walk by the lake, especially at like sunset or dusk. And if you do walk by the lake, you should definitely not talk to any woman because it could be an evil spirit trying to seduce you and she’ll drag you into the lake with her. Or else, if she doesn’t drag you into the lake, she could also go with you and pretend to be your wife or your girlfriend, but she’ll continue to bring bad things into your life and continue to haunt you without you knowing. And you’ll think you’re in love with her and meanwhile she’s destroying your life. So yeah, don’t find a girlfriend at Drunken Moon Lake”
The informant learned of this legend gradually over her time studying abroad in Taiwan, as whenever she would be around the lake, other people would warn her and tell her about the ghost that resided in it. She received pieces of the story in both English and Mandarin from different people.
The informant did not mention anything regarding the origins of this tale, or why people believed it, but it seemed to be taken quite seriously. Like many other horror tales and legends, maybe its origins had some practical application. Perhaps it was meant to deter young men from approaching the lake for some reason. Perhaps someone wanted to keep them away from flirting with the women around the lake, or keep them from trying to swim in the lake.
