Answer: According to the Administrative Measures for Business Files of Funeral Service Units, the following documents should be classified as funeral business files:

Category I: documents formed during the cremation of remains: (1) original or photocopy of death certificate; (two) the cremation certificate stub; (three) the funeral undertaker's signature of the cremation table and the certificate of receiving the ashes; (four) a copy of the valid identity certificate of the undertaker; (5) Other materials that should be filed.

category ii: documents and materials formed in the process of burial in cemeteries providing burial services: (1) original or photocopy of death certificate; (two) the contract for the burial of the remains; (three) the funeral undertaker's signature of the body burial table, business process sheet, etc.; (four) a copy of the valid identity certificate of the undertaker; (5) Supplementary contracts or agreements; (six) other materials that should be filed.

category iii: documents and materials formed during the burial or placement of ashes: (1) copies of death certificates or cremation certificates; (two) the ashes placement (burial) contract; (three) the funeral undertaker signed the ashes placement (burial) table, business process sheet, etc.; (four) a copy of the valid identity certificate of the undertaker; (5) Supplementary contracts or agreements; (six) other materials that should be filed. It is worth noting that the last item of each kind of documents and materials is "other materials that should be filed". This kind of clause, which some people habitually call "bottom clause", is a special clause set by legislators to prevent legislative omissions. Its content should be judged and determined by the executors of normative documents in accordance with the principles of normative documents and the specific circumstances of affairs. Taking the first kind of documents and materials as an example, combined with the specific situation of the funeral home business, we believe that in addition to the documents specified in items (1) to (4), the close relatives of the deceased entrust the funeral undertaker with the power of attorney, the funeral service contract, the confirmation photo of the special condition of the body, the screenshot of the short message urging the family of the deceased to come to handle the cremation affairs, and the explanation of the urging situation. If a funeral business has caused a dispute, the documents showing the occurrence and settlement process of the dispute should also be included in the funeral business files, such as mediation books and judgments.
