添加了一种前期织物——丝绸和一个建筑，建筑是专门生产这种织物的。
丝绸相比棉花，生产更加简单，只需要打开灯来吸引夜晚的蛾子就行，同时，丝绸美丽而脆弱，唯一的优点是隔热能力比较好。

An early fabric, silk, was added, and a building was built specifically for the production of this fabric.
Silk was simpler to produce than cotton, requiring only a light switch to attract moths at night. Silk was also beautiful and fragile, with the only advantage being that it had better insulation.
