Chinese culture fosters a deep sense of reverence for elders, a tradition instilled by Confucius. Even in death, family members are still expected to bow and pray to their elders in their graves. Family members are also expected to burn "hell" money (incense) to assist the deceased's passage to heaven, in addition to undertaking a variety of other rituals.
In contrast with Western customs of laying flowers, Chinese families typically bring food to the grave and leave it there for the deceased to "consume." These practices can vary based on the deceased's particular religious beliefs.
