Tat Tak School — built on a massacre site in Ping Shan, Hong Kong

Tat Tak School in the historic village of Ping Shan in Hong Kong's New Territories is said to have been built on the burial site of hundreds of villagers killed during clan warfare centuries ago. The school, which served the local community, was reportedly the site of numerous supernatural incidents during its operating years. Students and teachers described hearing children's voices in empty classrooms, seeing apparitions in the school grounds at night, and experiencing unexplained events such as desks being found overturned in the morning. The most disturbing reports involved children seeing ghostly playmates who were not visible to adults. The school has been closed and now serves as a heritage landmark in the Ping Shan Heritage Trail. The Ping Shan area is one of the oldest continuously inhabited settlements in Hong Kong, with the Tang clan having lived there for over 700 years. The region's long history of clan conflicts, disease, and the building of structures over forgotten gravesites has created multiple haunted locations, but Tat Tak School's connection to a mass grave makes it one of the most significant. In Chinese folk religion, building over burial sites without proper spiritual appeasement is considered extremely dangerous.
