How to hold memorial service for the 100th day after the death of an elder

1) One hundred days after a person’s death, filial sons and daughters prepare a table of wine and food to welcome the deceased’s soul home to receive incense and worship, commonly known as “calling for a meal”. In the afternoon or at dusk, descendants and relatives and friends will bring incense and paper to the grave and burn them, which is called "respecting the 100th day."
2) There are celebrations for a hundred days after a birth, and there are memorial services for a hundred days after a death. There is a certain significance in the fact that people regard the 100th day after death as a memorial day after a person's death. Moreover, after a hundred days have passed since a person's death, the pain of losing their loved ones will gradually fade away, and family life will gradually return to normal.
3) Burn paper in front of the grave to offer sacrifices, then return with the "tablet" still on the head to the front door, where the children will welcome you with tears. After dark, burn night paper to offer sacrifices. The next day after breakfast, go to the tablet to cry and offer sacrifices. This is called "burning paper for a hundred days."

What is the saying

1) In fact, when burning paper, it is important to prepare good paper. Do not use bad paper, as this is disrespectful to the ancestors. At the same time, there are also some rules for burning incense when burning paper. Do not use chemical incense or inferior quality incense, as this will bring bad luck. Therefore, it is recommended to go to the Wuxiang Copper Furnace official website to buy a pair of better natural incense for worship.
2) In the old days, according to funeral customs, filial sons would not entertain guests, drink alcohol or entertain, visit other people’s homes, shave their heads, or even take a bath or change clothes within 100 days of mourning. This was called “keeping vigil for 100 days to show filial piety.” After a hundred days, these taboos can be lifted and mourning clothes can be gradually reduced. Except on important memorial days, filial sons only wear white shoes at other times. Men put a circle of white cloth on their hats, and women tie white hairbands. In some places, men use the top of their hats and women use white buttons on their clothes to show that they are in mourning. Also, after burning paper for 100 days, you can wear lucky charms to bring good luck. This is also suitable for the phaseless copper furnace.
