Why can't the 999 ladder of Tianmen Mountain get up?

The reasons for the closure of the ladder in this scenic spot are as follows:

1. Affected by freezing rain and snow, freezing rain and snow will make the ladder surface slippery and smooth, making the climbing process more dangerous.

2. From September 20, 2022, due to the reinforcement construction of the walkway in Tianmen Cave, the walkway in Tianmen Cave was reinforced, the area in Tianmen Cave was kept completely closed, and it was forbidden to enter, and the escalator stopped running.
