Jiukong
Derived from the concept of 'Kongwang' (emptiness and loss), this day is traditionally avoided for opening granaries, receiving wealth, or taking in new members.
Jiukong is an inauspicious star derived from the concept of 'Kongwang'. In traditional date selection, 'Kongwang' symbolizes things coming to nothing, lack of harvest, or futile efforts. Consequently, old almanacs would list this day as one to avoid, particularly for activities like opening granaries, receiving money or valuables, and taking in new people (such as adoption or hiring). This is due to the belief that the day's energy field would prevent these matters from proceeding smoothly or lead to losses.
