When we were about to leave, a woman in strange clothes came up to us. She is wearing a shabby red dress and a necklace made of bones. Two snakes

Sitting on her arms. When we were about to leave, a woman in strange clothes came up to us. She is wearing a shabby red dress and a necklace made of bones. Two snakes sat on her arms. Snakes have represented mystery and prophecy since ancient times.

She asked us if we had her book. This book looks very old and has some strange words printed on it. You know, Zhouyi is a famous fairy in China. He is good at predicting people's future and is famous for it. He can do it with only a few small stones.

It's rare that I didn't use online translation. I've been looking up dictionaries and English books to determine those words and grammar. You must give them to me! I called twice. It will be unreasonable if you don't give me the right answer. I spent a lot of time.
