First, the family sets up a Baci tree (Mak Beng) made out of marigolds and candles.
Oranges, tamarinds, and other food may be placed at the base of the tree to attract any spirit to come and give blessing. The family then ties strings to the tree and invites a monk to come and bless the strings.
This Baci was for a new baby girl, so I tied a string on her...
...and Hong tied a string on her grandmother. They leave the strings on as long as possible to receive the maximum amount of blessing.
Then they dance.
