Answer: You can usually use incense, flowers, lights, clean water, rice, melons, fruits and other things. If it's not easy to do it, you can do it without a few or none, but you can't provide wine, meat and vegetables, let alone burn paper ingots in front of the Buddha.

2. There are no specific provisions. But durian doesn't taste very good, so I'd better not.
3. When individuals support Buddha and Bodhisattva icons at home, they don't need to tell the public, so they don't necessarily need to hold the opening ceremony. They only need to place the icon with piety and respect, and then provide it with offerings such as incense, flowers and fruits day after day to keep it fresh, neat and clean, so as to show the sacred atmosphere where the icon is located, thus arousing the moral heart of practitioners.
In order to keep the indoor air fresh, the incense should be fine. It is advisable to burn incense once in the family Buddhist temple. Don't light a lot of incense sticks, so as not to cause indoor air turbidity. Natural sandalwood and agarwood are the best fragrance types, and it is not suitable to use thread fragrance or stick fragrance modulated by chemical spices or animal spices. In the Buddhist temples of modern families, electric lights can replace candles, and sacrificial tables, incense burners and candlesticks should be cleaned frequently and new offerings should be provided. At the very least, there should be no dust or withered and rotten flowers and fruits. It is best to have regular morning and evening classes every day, at least burn incense and provide water in the morning and evening. Before going out and after arriving home, you should also worship the Buddha to show your gratitude, respect and concern.
