Because the southern mountainous area where Hong is located is the main source of spring water conservation and recharge in Jinan, the scenic spot is about 500 meters above sea level, the average temperature is about 5 degrees Celsius lower than that in the urban area, the mountain microclimate is obvious, the vegetation coverage rate of the scenic spot is as high as 97%, and the content of negative oxygen ions in the air is more than 300 times that in the urban area, so Hong is called "the hometown of springs, clouds, the world of flowers, the ocean of forests and a paradise for leisure and holiday".
