CHONGQING (CQNEWS) -- Tourists take photos at Zhongba Island in Mudong Town, Banan District, on May 13. Recently, the water level of the Yangtze River has dropped, and a large area of declining zone has been exposed on Zhongba Island. After ecological protection and restoration, dense green grass grew in the water-level-fluctuating zone, and the stretched sea of grass undulated high and low, dressing up the shoreline of the Yangtze River.
