Though the bronze tree was not damaged, preventive measures have been taken. The relics are valuable for archeologists and historians to study China's ancient history and culture.

The base of the tree was solidified, and a new bronze stick was hidden inside the trunk to make it stronger. Museum staff say with these measures, the relic will be able to stand a quake as strong as the one on May 12th.
