Introduction to Nantian Yizhu: Located about 1,500 meters southeast of Triassic Turtle Peak, it is a pillar-shaped boulder, more than 100 meters high and more than 400 meters above sea level. It looks like a giant. Looking closely at its appearance, it looks like "Erlang Zhenjun", which is said to be the incarnation left by Yang Erlang during his battle at Guifeng. In fact, it is more like a giant pagoda with clear levels, and on each floor there are many golden turtles stretching out their necks and looking around, as if they are also admiring the wonderful scenery of Turtle Peak.
