Bangkok hotel movies

I have seen a movie with similar plot, which was shot in Thailand (there are many such ghost films in Southeast Asia anyway), and I wonder if the subject is looking for it.

The plot is that the people of the female host are a group of pagans who believe in snakes, her father is a patriarch, and the female host worships the snake god (that is, she is reincarnated as the snake god), and later the people are eradicated by orthodox people. Only that woman survived to this day. Knowing the man, after knowing her true identity, he liked her and didn't abandon her. The man took her to his home in the city, and his girlfriend was jealous. She joined forces with the orthodox descendants to kill her and killed the man by mistake. She punished them, then revived the man, and it was all over.

This movie is called "The Snake Demon".

The original answer, if correct, is still acceptable. Thanks for your support.
