Theoretically speaking, Buddhism is about the origin. No matter what kind of blessing you want, you must worship the origin. Pearls, jewels and precious stones generally belong to the source of wealth.

Precautions for pre-Buddha offerings: flowers, fruits, food, tea and other pre-Buddha offerings are consumables and must be replaced daily; If it is still edible, it should be used for other purposes, or eaten by family members and should not be abandoned; If it is rotten or corrupt, do garbage disposal. As for whether it is an odd or even offering, there is no limit, and it is even in terms of symmetry. If it is limited to the relationship between material resources, financial resources, location and venue, there is nothing wrong with odd numbers. As for the category, the materials are subject to the range that everyone's financial resources may bear, and they are not perfunctory or extravagant.
