Turning left at Clear Sound Pavilion and passing by a stone bridge, visitors can find the hundred-meter cliffs on both sides join unexpectedly with only a small gap between them. Looking through this gap, the blue-sky turn into a straight line suddenly, hence the name Line of Sky. Sunlight from this gap makes the Black Dragon River simply glistening. An ancient twisted plank goes twists along the cliff, above this river. Walking up the hundred-meter plank trail, you will feel quite refreshed with the cool wind blowing all around you. |
