The car pendant made of cinnabar has multiple meanings:

In China’s traditional culture, cinnabar has always been regarded as having a powerful function of warding off evil spirits. Since ancient times, cinnabar has been used to make various items for exorcising evil. People believe that cinnabar can deter evil spirits because its color is as bright red as blood, and red has the symbolic meaning of driving away evil and bringing good fortune in folk culture. As a decorative item hung inside the car, the car pendant made of cinnabar can bring this power of warding off evil into the process of driving.
For example, in ancient times, many Taoist priests would use cinnabar when drawing talismans, because the talisman paper was believed to be able to drive away ghosts and suppress demons. The cinnabar car pendant is just like a small “amulet”. When the vehicle is driving on the road, it can resist the possible “evil qi” from the outside world, such as the so-called bad auras or “road evils”, and bless the driving safety.

During the driving process, there will be various potential dangers, such as poor road conditions and the illegal driving of other vehicles. The cinnabar car pendant implies that it can block the adverse effects brought by these risk factors and create a relatively safe driving environment for drivers and passengers. It is like an invisible guardian, giving people a kind of comfort at the spiritual level and enabling drivers to drive more at ease.

The red cinnabar itself represents festivity and good luck. The cinnabar car pendant hung inside the car can add a auspicious atmosphere to the vehicle. It symbolizes bringing good luck to the passengers. For example, when people go out to handle affairs, they can go smoothly, and during the journey, they can encounter wonderful things.
Just like during the Spring Festival and other festive holidays, red elements are everywhere. The red color of the cinnabar car pendant also implies continuous good luck. Whether it is on the way to work, on a self-driving tour or visiting relatives and friends, it embodies people’s good wishes for a safe journey and everything going smoothly.

Besides good luck, the cinnabar car pendant also implies the blessing for the health of the passengers. It symbolizes that it can protect people from being invaded by adverse factors such as diseases during the driving process. Especially for those who drive for a long time or often travel by car, the meaning of this blessing is even more important, hoping that they can always maintain a healthy physical state.
