Introduction to watching the sun on the top of the mountain: There are two mountains on Nanji Island, one is called Nanji Mountain, 192 meters high, and the other is called Dashan, 229 meters high. These two mountains are entangled together, forming Dashao in the southeast and Mazuao in the northwest. Standing on the top of the mountain, you can see the vast expanse of cloud waves in the East China Sea. Especially when watching the sunrise, a red sun jumps out on the horizon; when the red sun sets in the west, the sky is filled with colorful clouds, gradually disappearing into the vast twilight, it is particularly spectacular.
