In Taoism, it is known as the Three Pure Incense, representing the Three Pure Ones: Yuqing (The Heavenly Lord of Primordial Beginning), Shangqing (The Heavenly Lord of Lingbao), and Taiqing (The Heavenly Lord of Dao De).

4. Common types of incense used during Tet
Typically, during Tet in Vietnam, people commonly use the following three types of incense.
- Stick incense:
This type of incense dates back to the Song and Ming dynasties. It has a long burning time, which is why it is also called longevity incense or immortal incense.
Stick incense comes in two types: one with a core and one without. Generally, the incense used in households is small stick incense, which burns for a short period and produces little smoke. Larger stick incense, with a longer burn time, is typically used for offerings at temples and pagodas.
- Coil incense:
Compared to stick incense, coil incense burns for a longer duration. Coil incense can be categorized into two types: large coils, which can be hung directly for burning or placed on an incense rack within an incense burner for use in temples, shrines, or ancestral halls.
Smaller coil incense is used for offerings or personal meditation and is burned on a Buddha altar, not on a family altar.
- Tower incense:
This type of incense is crafted from agarwood, sandalwood, cloves, frankincense, and water, then shaped into small pointed cones. Tower incense is typically placed directly on a flat incense dish for burning or burned in a censer where the ash is collected.
Once burned, the ash from tower incense forms a pointed cone shape, which does not scatter, making it easy to use. The burn time for tower incense is shorter than that of stick or coil incense, which is why it is commonly used in households.
Note:
Regardless of the type of incense chosen, it is important to use incense made from natural materials. Avoid incense made with chemicals, as they harm health and do not convey the proper respect for deities and the deceased.
How to store incense: Incense should be kept in a fixed, clean, and dry location. When purchasing, choose incense with sealed boxes. Do not leave unburned incense on the altar. Handle incense carefully to avoid dropping or spilling it.

5. Important considerations when lighting incense during Tet

- Carefully arrange the offerings (fresh fruit, clean water) before lighting the incense.
- Use incense made from natural ingredients, and avoid incense that contains chemicals as it can harm everyone's health.
- Store incense in a dry, clean place. It's best to keep it in a tightly sealed box.
- Handle the incense gently to avoid spilling or dropping it onto the ground.
- Regularly clean the incense spoon, incense burner, and the incense box.
- The distance between the person and the incense bowl should be just right—not too far or too close.
- Only light one stick of incense. If using a new incense bowl, you may use three sticks. Avoid lighting a whole bundle of incense, as the smoke becomes too dense, making the air polluted and suffocating during the ceremony.
- After the offering ceremony, if incense ash falls, use a clean cloth to wipe it. Do not blow on the ash with your mouth.
- If the incense goes out, you can relight it (in temples, they collect it into bundles for burning). Do not discard it on your own.
- Do not burn too many incense sticks during prayers, especially if the offerings are not replenished. Folklore suggests that inviting ancestors to consume old offerings does not show sincerity.
- The act of lighting incense, then blowing on it, waving it, or extinguishing it by fanning, followed by placing all three sticks or even a bundle into the incense bowl is improper and should be avoided.
- To avoid disturbing the incense bowl, do not carelessly add a metal holder into it for circular incense burning. If used, incense coils should be placed in a dish instead.
- Placing incense sticks in food for offerings can lead to poisoning, as the incense sticks often contain harmful chemicals.
- Homes with young children should avoid excessive incense burning, as it can negatively impact their respiratory system.
