Is it better to burn incense for the dead three or one?

Many people burn incense to the dead, and many people worship. So what's the point of offering incense to the dead? Incense the dead, three or one?

Incense, ostensibly for the dead, is actually for yourself. One represents silence, and three represents the silence of body, mouth and mind. So all three can be used, which means that you have a clean heart to worship each other. The more incense, the better. The bigger the better. The most important thing is the person who burns incense. Incense is just a way to convey people's inner feelings.

Summary: Incense is mainly an expression, giving the dead an expression. One incense stands for purity, and three incense stands for purity of body, mouth and mouth, so there are usually one or three incense sticks.
