Standing by the bank of Dianchi Lake, the mist of the early morning has not yet dissipated, the lake is like an uncarved moyu, lying quietly between the mountains. As the "Pearl of the Plateau" in Yunnan's population, it does have the courage of the sea - 500 miles of smoke and waves, the water and sky blur the border, only occasionally skimming red-billed lizards, with wings to break this silence. Riding along the newly built greenway, one side is the red mesh forest and the other side is the endless lake. The 71-kilometer greenway is like a ribbon, gently stringing wetlands, flower fields and ancient villages. When you walk to the "Bridge of Grass", there is a rustling in the reeds, as if you can hear the rhythm of the lake breathing. The dusk of the century-old fishing village seagulls is the most unforgettable - the old house floats out of coffee, young people hold their cameras to watch the sunset, new and old in the sparkle quietly reconcile. People always say that Dianchi has seen too many stories: Zhuang 𫏋 into the boat, Sun Yongweng Changlian in the vastness, and the sigh when the blue algae flooded. Now the water quality has been maintained for seven consecutive years, and the salvage team's boat is no longer piled up into tons of filth. The lake of course remembers everything, but it chose silence, and history was settled into a grain of sand on the shore, and a bird song in the wind. When I left, I looked back and saw that the west mountain was lying on the lakeside like a sleeping beauty. Suddenly I know why the ancients called this "Bohai" only the heart of the sea can turn the vicissitudes into gentleness, so that every passer-by can see their reflection.
