During Undas, family members visit the cemetery where the body of the loved ones rest. It is believed that by going to the cemetery and offering food, candles, flowers, and sometimes incense sticks, the spirit of the loved one is remembered and appeased. Contrary to common belief, this visitation practice is not an imported tradition. Prior to the establishment of coffins, pre-colonial Filipinos were already practicing such a tradition of visiting burial caves throughout the archipelago as confirmed by a research conducted by the University of the Philippines. The tradition of "atang" or "hain" is also practiced, where food and other offerings are placed near the grave site. If the family cannot go to the grave site, a specific area in the house is provided for the offering.
