What is the difference between cremation and burial?

Burial is to bury a person directly in an underground coffin after death. Cremation is cremation after death, and then the ashes are buried. Old people don't like cremation mainly because people have died since ancient times in China, and they should keep their whole bodies. People in China attach great importance to the integrity of the body after death. In ancient times, people who were beheaded or beheaded had to ask a tailor to repair their bodies before being buried. China people have had this tradition for thousands of years. People are cremated, and what they burn is just a pile of ash, which the old people can't accept. Nowadays, people have received modern education and their thinking has changed. But the elderly, especially those in rural areas, are still very persistent.
