The octagonal gold plate is a traditional Feng Shui tool that is widely used in Feng Shui layout and placement. However, there are some taboos that need to be observed when using octagonal gold plates to avoid adverse effects. First of all, octagonal gold plates should not be placed in bathrooms such as the kitchen or toilet. This is because the symbolic meaning of the octagonal gold plate is to bring wealth, and bad auras such as odor, yin and moisture are easily produced in the bathroom, which will affect the normal function of the octagonal gold plate. Secondly, the octagonal gold plate should not be facing the door or window. This is because the function of the octagonal gold plate is to promote wealth, and doorways and windows are the channels for wealth to enter and exit. If the octagonal gold plate is placed directly against the door or window, it will cause the loss of wealth and go against the trend. Third, the octagonal gold plate should not be placed in private spaces such as bedrooms or study rooms. This is because the strong aura emitted by the octagonal gold plate will affect people's mental and physical health, especially in places that require a quiet environment such as sleeping and studying. The octagonal gold plate will have a negative impact on people. Finally, the placement of the octagonal gold plate also needs to be selected according to the individual's zodiac sign and horoscope. Different people have different suitable positions. At the same time, the octagonal gold plate needs regular cleaning and maintenance to keep it clean and in good condition. In short, the octagonal gold plate is a Feng Shui tool with profound cultural connotations and strong symbolic significance. Some taboos and precautions need to be observed when using it to achieve good Feng Shui effects.
