《宋史·志·卷三》
匏瓜五颗星又作瓠瓜。在离珠北面，是天子的果园，它西边的觜星主管后宫。星不明亮，那么皇后失去权势；星不全或动摇，是盗贼；星光亮，那么年成丰收；暗淡，那么果实不丰收。
匏瓜五星一作瓠瓜，在离珠北，天子果园也，其西觜星主后宫，不明，则后失势；不具或动摇，为盗；光明，则岁丰；暗，则果实不登。
The five Pao Gua stars, also known as Hu Gua stars, are north of the Li Zhu star. They constitute the emperor's orchard, and the Zi star to their west presides over the inner palace. If the stars are dim, the empress will lose power. If the stars are missing or move, there will be bandits. If the stars shine brightly, the year's harvest will be bountiful. If they are dim, the harvests will be poor.
