Snow White and the Seven Dwarfs

I read an English book of the title named Snow White and the Seven Dwarfs. This story is a happy ending. Snow White is a very beautiful princess. However, the witch cannot permit that. She tries to kill Snow White. However, Snow White survives, and begins to live in Dwarf's house. The witch who knew that made Snow White eat the poison apple and killed. However, Snow White is helped by the prince. I thought that it was only one time that the witch came to Dwarf's house. However, the witch had come to the house three times. I think that Snow White is a little foolish. Because Snow White seems to be killed by the witch though the Dwarfs are drawing attention.
