Bainiu Dujiang Introduction: After the long-standing Jialing River flows through the beautiful Peng'an County, due to the erosion of the river water and the deposition of sediment, two huge islands in the river are formed: one is round, like the bright sun High shine, floating light leaping into gold. A curved one, like a crescent moon in the sky, a silent shadow sinking into the jade. The common people call them Sun Island and Moon Island respectively. This is a paradise for cattle and a paradise for birds. From late spring to early autumn, in the early morning, hundreds of cattle swim in groups from both sides of the Jialing River to the island, grazing on the grass and enjoying themselves; at dusk, the cattle do not need to be shouted at by the shepherd boys, but dive into the water and swim back to the shore. In the morning light and under the setting sun, the rivers depend on each other and bull heads surge, forming an ecological wonder of a hundred cows crossing the river, which is rare in the country.
