The 49-day worshiping ceremony ( Sino-Vietnamese : Chung inter) is a form of belief, at the same time it is also a very important ceremony for the death of the survivor. This is an opening ceremony 49 days after the death. 

This custom is  based on the  Vietnamese Buddhist theory  : Soul after death has to go through 7 judgments, each lasting 7 days. Then the soul has to go through a large power in the underworld, after 7 weeks the soul will be saved. This is the time to bring the dead's soul to the Buddha's door. This is an event very important in worship continue  to mourn  for  the Vietnamese , to express sincere reverence, remembrance of the mercy and the living to the dead.END=NAM MO SHAKYAMUNI BUDDHA.( 3 TIMES ).GOLDEN AMITABHA MONASTERY=VIETNAMESE BUDDHIST NUN=THICH CHAN TANH.AUSTRALIA,SYDNEY.13/10/2020.
