Kingdom of Funan
The "sbai" of Cambodia was introduced from ancient India as it resembles Indian sari. There are related mythologies in the Khmer culture concerning the history of "sbai", which was likely introduced during the Kingdom of Funan alongside chang kben in the first century AD. The "sbai" is mentioned in the legends of Preah Thong and Neang Neak. In one scene, Preah Thong clings to a piece of cloth worn on the Nagini in order to make the journey to the Nāga's kingdom; that piece of cloth is a "sbai". In that tale, the "sbai" is symbolic of the tail of Neang Neak, the Naga princess.
