Head northwest of Treasure Hill and downstream along the Xindian Riverbank, you will find a drainage pipe that’s part of a wastewater treatment plant. Water used to gush forth from the pipe in an arc like a mini waterfall, forming a pond. The discharge contained particles filtered out by the water treatment process. Wastewater in name, it was actually quite clean. The pond was too small for swimming, but it was perfect for a soak and a lively chat with friends, five or six at the most, as water only went as high as the waist or chest. It used to be the favorite secret meeting place of children growing up in the village. These days, you can still see hidden within the bushes numerous rows of pipes. There weren't any bike lanes, so to pass through the jungle of weeds that stood between us and our secret ＂base,＂ we had to rely on the large pipes for guidance.
