Palms pressed together, the nine-year-old boy stood in front of a medium with a long metal chain draped over his shoulders and arms.
After a friend of the medium posted pictures of this ritual (above) on Facebook last month, they went viral.
A netizen sent the pictures to Chinese evening daily Lianhe Wanbao, expressing concerns that the ritual might be dangerous for the child.
When contacted, the chairman of the Taoist Federation, Mr Tan Thiam Lye, said the ritual is safe and commonly practised.
The boy's father also said it was safe and his son had volunteered to do the ritual.
