The Hungry Ghosts and the Significance of Number 4

Traditional Chinese culture upholds centuries-old beliefs that include communicating with spirits and warding off evil. The concept of "hungry ghosts" who torment unhonored spirits after their death is prominent, and this is celebrated during the Ghost Festival in the seventh lunar month. These beliefs also influence everyday life details, such as avoiding the number 4, which is pronounced "sì" and sounds similar to the word for "death." Consequently, floors and numbers that contain this digit are often avoided. This extends to choosing gift colors and interpreting the symbolism of numbers and other objects in accordance with these beliefs.
