Red chamber fortune telling

According to Chen, when her mother was pregnant in October, she dreamed that a white-haired old man said to her, "You will have a daughter, and you will name her Ba.". Because the word "bang" could not be found in the dictionary, her mother named her "Xiaoxu" and she was born in the early morning. When Chen grew up, he heard about it from his mother, so he looked it up in various dictionaries and finally found it in Ci Hai, which was Xiangmu's name.
