An Ling (安灵)
An Ling is an act of filial piety by the descendants according to Taoist / Buddhist beliefs.
For An Ling, descendants have to prepare a table to place the tablet, picture, joss pot and daily food offerings in their residence. The offering of joss sticks, drinks and food have to be carried out daily for the next 49 days.
Ji Ling (寄灵)
Ji Ling is the same as An Ling, but just that the tablet, picture, and other items are placed in the temple / monastery / columbarium where the caretakers or monks help to carry out the daily offerings and chanting.
