Ah Pek at Clarke Quay (Cha chun tau)

Birthday celebrations for Twa Ya Peh at Liang Hiang Tua temple Clarke Quay
The troupe of devotees led by medium Ah Hui perform rituals to cleanse the district of negative energies and empower the guardian spirits with offerings. Despite the heavy rain, Hell money is cast to the wind and ritual petitions burned. The black flag (Orh Leng Kee) is carried to signify the presence of the Deity whose duties in Hades involves policing any misbehaving ghosts.
