In Chinese calendar, every year there is a day in summertime earmarked for beating 'petty persons' (i.e. hostile parties). This day is called Jingzhe, overlapping either March 5th or the 6th in western calendar.
The main objective of the beating petty persons is to eliminate their vicious influence, while invoking aid from "honorable person" for the ritual's recipient who may or may not be the actual performer of the ritual.
In Hong Kong, underneath the Goose Neck Bridge in Wan Chai is a well-known locale for people exercising the ritual, but it is a mistaken idea if it is thought to be an exclusive venue, as one could easily find people everywhere performing the same ritual at street corners in respective neighborhoods. The Bridge draws particular attention simply because it gathers a number of elderly women, working as 'professional beaters'.
