What is the funeral culture of China's historic Mongolian people?

Old Mongolian people, especially the poor people in the pastoral areas, their funerals were relatively simple. Before the death of a person, the whole family and even the relatives and friends are on the side of the person. After death, the whole family mourns, usually not set up a hearth, do not set up offerings, do not wear mourning clothes, do not burn paper, do not use music, do not give friends and relatives through the obituaries. But almost always invited lamas to read scriptures. The deceased did not write a will, only verbal instructions, such as livestock left to someone, the bones sent to where.
