Thousands of believers and guests from both Chinese mainland and Taiwan attended the folk culture activity.

The goddess was often associated with Chinese Taoism. It is believed that she was the dispenser of prosperity, longevity, and eternal bliss. Her popularity grew across the China as a result of the opening of the Silk Road.
