Mansion Wei the Rooftop
10♌19 to 27♌16
Those born under the Wei constellation are impatient and stubborn. They are kind-hearted but guileless, which can make them vulnerable to being taken advantage of in interpersonal relationships. Their nature is quite polarized, ranging from good to bad, and their strength depends on how they choose to channel it.
It represents the moon and the swallow. It is the fifth constellation in the north, located at the tail of the tortoise and snake, hence the name “Wei” (meaning danger). In battle, the rear guard is often in danger. Wei means high, and high places are dangerous, so the Wei constellation is often considered inauspicious.
When the Wei constellation is in power, it is not auspicious. Disasters and plagues are inevitable. All construction and building will be unfavorable. Disasters will outnumber auspicious events, and things will turn into calamities.
The presence of stars representing tombs, empty beams, and covered houses within the constellation of Wei is considered inauspicious, reflecting the unease felt by the ancients during late autumn and the approaching winter.
The character 危 (wēi) means “above the roof beam.” The Shiji (史记) quotes the * Liji* (礼记) as saying, “Walking on the roof beam in the middle of the house is to avoid soldiers.” The Shiji (史记) also states, “危 (wēi) is a roof.” The * Jin Shu* (晋书) states, “The three stars 危 (wēi) govern the roof structure of the celestial market.” These three stars resemble a pointed roof.

Dangerous Moon Swallow
People born under this sign are prone to alcoholism and licentiousness. They are hardworking but also stubborn. Their friendships are short-lived and unresolved. They can handle affairs and administer antidotes, but they are prone to anger.
Preparing, taking, and administering medicine is very auspicious. They also suit serious and wicked endeavors, such as digging rivers and ponds, planting hemp and beans, sending merchants to collect taxes, appointing officials, and hiring doctors. They also suit stockpiling goods, building boats, brewing wine and other beverages, and trading. It is auspicious for merchants to return home, but not for spending money.
Wei Advice
While it’s true that it’s good to have a big tree to lean on, what belongs to others may remain theirs for a time. They may share it with you temporarily, but it will never truly belong to you. Your own tree, on the other hand, requires hard work and time to grow. But no one can take away what belongs to you.
Sometimes saving money can feel difficult or terrifying. It’s important to understand that no one in this world has unconditional freedom. Ultimately, you’ll need to give something in return. If you can’t face your desires and, in return, exercise self-discipline and control, your health might become the price of that exchange. The pleasure is truly exhilarating, but the suffering can be devastating.
There’s nothing wrong with not forcing yourself to do things you’re not interested in. However, you must be prepared to handle the aftermath when you withdraw and plan your next step. Be a little more cautious, and one day you’ll thank yourself for your patience. You are kind and innocent; protect yourself, because you will bring much beauty to this world. [2]
