Burning Tanabata is one of the important festivals in Chinese traditional culture, which is usually held on the seventh day after the death of the deceased. When burning July 7th, sacrifices usually include chicken, duck, fish, meat and so on. These sacrifices can show respect and memory for the dead.
However, there is no need to take these sacrifices back to eat. In modern society, people pay more attention to health and environmental protection, so the way to deal with sacrifices is more environmentally friendly and healthy. If you are worried that the sacrifice is unsanitary or wasteful, you can choose to dispose of it properly or donate it to charity.
In short, whether the sacrifice burned on July 7 is recovered depends on personal wishes and actual conditions.
