The discovery of substantial tin deposits in the Kinta Valley attracted a diverse influx of immigrants, particularly from China, who sought their fortunes in the lucrative mining trade.
The town's name, "Pusing," meaning "turn" in the Malay language, is believed to derive from the winding nature of the Kinta River that flowed through the area.
The British administration recognized the economic potential of the region and invested in infrastructure, including roads, railways, and bridges, to facilitate the transportation of tin ore from Pusing to the coast for export.
Numerous tin mines, dredges, and processing facilities were established, attracting workers and contributing to the town's growth.
The North-South Expressway connects the town to major cities in Malaysia, making it convenient for travelers to reach Pusing by car or bus.
