Why is the old county town of Beichuan closed?

In the summer of 20 13, the old county town of Beichuan was hit by torrential rains and mudslides one after another, which caused some stations to be damaged and closed. In order to ensure the safety of the ruins of the old county, the headquarters of the old county arranged personnel to be on duty day and night to detect floods, and immediately notified relevant departments when finding dangerous situations, and enabled flood control troughs, safety guardrails and fences to prevent the ruins from being damaged by floods.

After the site area was forced to close in the summer of 20 13, the management center immediately invited experts to formulate a protection fallow plan, organized manpower to clean up and detoxify the flooded area and dredge the raised riverbed. After a month's efforts, we finally reached the conditions for reopening in August 15.
