You can stay at home for a few days after death.

Life and death matter. Nothing is more important than life and death. How to help dying people and how to deal with them after death, I recommend reading a book: chìzhng xzhī (also known as the dying notice), which is the vernacular version of Jin Zu's Reunion. This book tells how to take care of the dying and help the dead.

The book What You Should Know Last is easy to find on the Internet. It will be very helpful to download it and read it carefully.

How to deal with people after death and how to stay at home for a few days are detailed in the book: 1. If they die in the hospital, don't send them to the freezer immediately and apply preservatives (the biggest thing in life) to avoid the pain of the dead becoming an' ice hell'. If you are afraid of its rotten smell, you can burn incense or put ice cubes, but you must not put ice cubes. 2. After the body is completely cold, stop for two hours before taking a shower and changing clothes (final explanation). Don't touch it at will. Please ask someone with knowledge and experience to do it within 12 to 24 hours after your death. If not, family members still need to be cautious. If the joints are stiff, washing them with a hot towel will naturally soften them. 3, and cremation should be seven days later-(the biggest thing in life) to prevent the possibility of yang return, unless there is serious trauma or death.

Due to the limitations of modern family conditions, it is difficult to cremate after seven days, but it is best to stay for one or two days. Of course, it also depends on the local climate conditions. If the weather is hot and humid, it depends.
