We, the people of Tap Ninh, immediately knew something was wrong. We discussed it with the Gia Van Commune authorities. The entire village worked together to clean up trash along the banks, collecting plastic bottles and bags left by visitors. Many households stopped using chemical pesticides and switched to growing organic lotus vegetables. The commune also coordinated with a nearby factory, requiring proper wastewater treatment. On one occasion, Mr. Ty — a veteran boatman — even recorded unusual foaming water and reported it to the commune immediately.

Gradually, the lake water became clear again. The lotus bloomed, the herons returned, and fish spawned among the aquatic plants. Visitors increased, yet the villagers still reminded each other: "This water not only nourishes the birds and fish, but also nurtures our own hearts."

Whenever tourists ask, "Why is the water so clean here?" we simply smile and say: "Because our village knows how to protect it. If each person does their part, the water will heal itself."
