On a trip to the Philippines, there is a place that strongly recommends that you plant grass: the Kawa Mountain Waterfall in Cebu Island. This is not a natural view of the waterfall, but a pristine jungle canyon that jumps over the cliffs and valleys. 4-5 hours in the whole process, except for life jackets and helmets, everything is "resigned." Crossing here, suddenly a step jumped from the top of the cliff into the valley at the bottom of the ground, feeling the heart's sense of stagnation in the throat. Suddenly, he ran down the stream, played a slide on a smooth cliff, and then fell into the valley. Its hard to go through a few hurdles and jump into the valley again to dive and swim. Then go back and forth, risk one after another, the inner volatility continues to increase, and the beating heart is constantly being challenged. That day, my physical strength was almost exhausted, but it was too exciting and fun!
