No. 10, Jalan Cina, 34750 Matang, Taiping, Perak.
Coming from Ipoh towards the north, exit at Taiping/Changkat Jering toll exit. Then follow the road sign to Taiping town, passing by Changkat Jering, and going along Jalan Simpang (Simpang's a small town before Taiping, btw) until you reach the traffic lights at a crossroad. Turn left towards Matang/Kuala Sepetang, and you'll soon cross an overhead bridge, overlooking the North-South Highway.
A short distance away, and you'll reach a 90 degrees right curve, followed by a turning on your left into Kampung Matang. Take the NEXT turning to the left instead, and you'll soon reach Matang town, with a Chinese temple on your left. Directly opposite the temple.
