Remembering a dead person

In Zimbabwe were i come from when someone dies there always have a funeral service and everyone is invited to come. After the service they have a burial ceremony where they help the grieving family burry their loved one. The day after the burial family members and close friend to the person who died gather around at the dead person house and the share staff that the person who died left and sometimes the dead person gives another person they trust instructions to share specific staff with just friends and other staffs such as houses, cars, or property they owned to be shared amongst family before the person dies. After a year that person dies they have a gathering with the whole family and just remember the dead person and to celebrate what the dead person had accomplished before they died. Yes i know it is a bit confusing and sometimes i also get concfused with the whole process.
