The 10,000-meter tunnel is on the top of Daming Mountain. Take the cable car. You can go down to the 10,000-meter tunnel without walking a short distance. This tunnel was left by mining before. Before the suspension plank road was not repaired, this 10,000-meter tunnel is the only passage to the top of Daming Mountain! The cave was very cool. I used to have a lot of mountains, but the first time I saw such a long tunnel on the top of the mountain, it was really amazing.
