书房与主卧之间用移门分隔，不占用内外空间。业主对隔音没有要求，又考虑空调的节能性，此处移门是最佳选择。

Study and the master bedroom are separated from the door, and the internal and external spaces are not occupied. The owner has no requirements for sound insulation, and considers the energy saving of air conditioners. The movement of the door is the best choice.
