I specialize in Guan Gong's cultural products. My family has always believed in Guan Gong religion, and the customs in different places may be slightly different. Give you some advice: generally, you can choose fruits and snacks, such as apples, bananas, oranges, melons, kiwis, biscuits, snacks, etc., and you can share them with your family after offering them. That's good. If there are particularly important matters, you can prepare some cattle, sheep and fish, which is more grand. On the fifteenth day of every month, you should burn incense, pray and offer sacrifices. Usually if you have something to petition, you have to burn incense.
