Why Is Residential Use Discouraged Above Shops in Arcaded Buildings?

Arcaded buildings (Qilou): Commercial shops are located on the ground floor, with residential spaces above. According to traditional folk beliefs, it is not recommended to use the upper floors as bedrooms or studies; they are considered more suitable for storage rooms.

With people constantly coming and going on the ground floor, the airflow and activity can be noisy and unsettled. Traditionally, this is believed to create an unstable energy environment for living spaces above and cause wealth energy to disperse.
