Who knows what this movie is called?

I want to know about a movie I saw when I was young. I remember it was from Thailand. I forgot about it. There was a huge giant (siren) on the sea who caught a man who could play the flute. She took the man to her cave and turned into a beautiful woman, wanting to do it with the man. Then, the two of them had a child. One day, the man took his child to the beach and found three mermaids. The three mermaids were a family of three. The daughters were very beautiful. In the end, the siren wanted to kill the mermaid. Her husband, the man who played the flute, sat on the ground and played his flute. He blew his wife, the siren, to death. Who knows about this movie?
