Many Vietnamese believe the deceased visit them during the seventh lunar month, the Month of the Ghost, and make ritual offerings. 

The Month of the Ghost peaks in the middle of the seventh lunar month, which falls on August 15 this year. On this day, many families in Vietnam lay out food and joss paper as offerings to the deceased. They also go to pagodas for praying to avoid bad lucks.

The 15th century Quan Su Pagoda is a place of pilgrimage for many Buddhists during the seventh lunar month. The pagoda, also the headquarters of the Buddhist Sangha of Vietnam, is at 73 Quan Su Street, Hoan Kiem District, Hanoi.

On the morning of August 12 (12th of the seventh lunar month), the main hall of Quan Su Pagoda fills up with devotees. The place echoes with the sound of chanting as monks perform the ceremony.

A plate of joss paper is passed among the worshippers and finally placed on the main altar.

There will be prayer sessions at 7:30 am on August 18, 28 and 29 (lunar July 18, 28 and 29) at the pagoda when rituals are performed to pay homage to the wandering souls and commemorate ancestors.

Tran Thi Tam of Ha Dong District said: "I pray for health and peace for everyone and for the lost souls to end their sufferings. I visit many pagodas year round, but for the seventh lunar month every year I always come to Quan Su Pagoda since it is one of the biggest in Hanoi."

These days Tran Quoc Pagoda in Hanoi is crowded with hundreds of Buddhist faithful. The ceremony to commemorate ancestors was performed on August 8. On August 15, full moon day of the seventh lunar month, the pagoda will organize sermons and prayer sessions.

Tran Quoc is located on a small island near the southeastern shore of the West Lake.

On August 12 worshippers recite Buddhist sutras to show repentance and gratitude to parents and the teaching of the Buddha.

Besides worshippers coming to the ceremonies, Tran Quoc Pagoda also receives many tourists as a popular sightseeing place in Hanoi. Visitors are advised to not enter the main hall while the chanting takes place though they can stand outside and take photos.
