"In traditional Chinese funerals, there are many decorations to
represent your sorrow and memories to the deceased. For example,
flower wreaths and memorial banners, and they used a lot of flowers
to decorate the repository hall. My grandmother is a Christian.
Therefore, the whole funeral practice is a mixture of traditional
Chinese customs and Christian religious procedures. My grandmother
died at the age of 98. When a person died after age 80, this is a
person with long life. This person should be proud of himself (or
herself). Therefore, the funeral would be different from an
ordinary procedure. For example, in ordinary funeral practice, all
the things used in the ceremony are white. In a funeral for a
person who died after the age of 80, there would be some red (color
of good luck) in the decoration. Using both white and red colors in
the practice expresses the mixed types of feeling (sorrow and
happiness). To represent joyful feelings, people would write
memorial banners on red paper instead of white cloth. Therefore,
banners on either red or white fabrics were used in my
grandmother's funeral."
