What do you mean by offering sacrifices and incense?

Sacrifice means offering sacrifices to people or gods you respect with things you like, such as ancestors, gods, buddhas and bodhisattvas. Xiang is also one of them. The "ten offerings" emphasized by Buddhism refer to ten items such as incense, flowers, lamps, water, fruits, tea, food, treasures, pearls and clothes, all of which are offerings to the Buddha. You can choose freely according to your own needs. It's just that incense has a special initial role and a strong sense of ceremony. It can be used independently or in a centralized way, and placed at the front of all ceremonies.
