The Delusion Door, also known as the Blocking Door or Du Men (杜門), possesses moderately auspicious qualities despite its association with obstacles and darkness. It signifies hindrances, lack of opportunities, and mysterious outcomes, yet depending on its application, it can yield positive results. Suited for stealthy activities like hunting, and hiding from others, it also facilitates getting away from unwanted attention to focus on activities such as studying or becoming low profile in meetings.

Located in the Xun Palace of the southeast sector, the Delusion Door embodies the mysterious and unexpected, often leading to setbacks and blockages. Associated with Wood and Wind, it exists in a state of tension between opposing forces, symbolizing stagnation and a lack of growth opportunities. While generally inauspicious, it may offer an escape from immediate threats and prove beneficial for hunting. However, its weakened Wood Element renders it ineffective for most situations, making it unsuitable for wealth pursuits, general affairs, or encounters with familiar individuals who may struggle to recognize one under its influence.
