Burial together is an ancient custom in China. To this day, people often like to bury dead couples or lovers together, especially for their parents, even before their death. Husband and wife have deep feelings when they are alive, and they will continue to be companions after death. From the perspective of children, it is also a great comfort to see parents "born in the same place and died in the same place".
Joint burial, an ancient custom, means that husband and wife are buried together after death, which is called joint burial. This custom has been circulating in China for a long time and can be traced back to primitive society.
