Introduction to Jiulong Waterfall: The pool water originates from mountain spring water. It is sweet and clear, crystal clear, and flows all year round. In spring, the trickle is trickling, and the reflection is clear; in summer, the waterfall splashes and the wind stirs the suspension. The stream looks like a colorful giant dragon, flying down three thousand feet, just like scattering beads and spraying snow, which is extremely spectacular; in autumn, the blue waves are rippling, and the scales are shining; in winter, the ice bamboo shoots hang upside down, holding beads and spitting out jade. The length and size of the waterfall are rare in Shandong Province, and it is known as "the first waterfall in Qilu".
