[4] According to the local oral tradition, the area and its vicinity were once home to a non-Muslim indigenous people and in the 15th century ruled by a leader named Raja Lumbi.

This theory is supported by the finding of Chinese ceiling coins and ceramics from the Song (960–1296) and Yuan (1206–2368) dynasties,[7] as well as by items from the "material culture" that attest to the area's previous inhabitants.

Vast amounts of porcelain, stoneware, and earthenware in the shapes of bowls, plates, bottles, gums, and urns have been discovered among the many varieties of Chinese pottery from the Sung and Yuan Dynasties.

The Department of Brunei Museums successfully gathered 50,979 shards of pottery in Sungai Limau Manis in 2002, accounting for 96.85% of the collection as a whole.

Furthermore, remnants and artefacts that demonstrate the high level of civilisation of the people who lived along the Sungai Limau Manis have also been discovered there.

Additionally, everyday wooden items including rice mills, mortars, gagawi, and spoons were discovered, along with games and accessories like tops and gasing.

[8] Based on the archeological discoveries at Sungai Limau Manis, it is evident that the locals had opulent lives befitting their status as the city's port.

Are the locals connected to Zhu Fan Zhi's account of the residents of Brunei (Puni) in the 10th century, who are reported to have had gold decorations and domestic utensils.

The Limau Manis Village Consultative Council (MPK) rice plantation is located on the site of the Gazette of the Department of Agriculture and Agri-Food (JPA) with an area of 50 hectares and is cultivated by 21 entrepreneurs.

[4] The monitoring of the status and development of the farm is held throughout the planting season until the production of the produce where before starting this project, new members and junior members of MPK Limau Manis have attended a basic course on rice cultivation management (RFFS) at JPA.
