Going Taiwan from 9/12-14/12. Can I wear slipper instead of shoe and is it very cold in the night?

Hi, although it will be comfortable and pleasant, slippers are not proper, maybe they can be worn in the room. The average temperature then will be about 16-18C. According to the weather records of the past two years, it may rain then. Therefore, at nights, you may feel cool, but not that cold. Anyway, an overcoat may need to be taken along.
