Zhaohua is a historic town of Sichuan province in China. On May 12th, 2008, a devastating earthquake measuring 8 on Richter scale struck Wenchuan, Sichuan province. In the process of recovery, 9 damaged historic buildings were demolished, 26 historic buildings were regenerated with new materials and 22 new buildings constructed in historic district. The purpose of this report is to study the space change of historic district during the process of recovery, and then attempt to get some lessons from the change of traditional space. We conclude that the emergency management is necessary for the whole environment of the historic district, in order to preserve the traditional space in post-earthquake. In China, although some principles on the conservation of historic districts were in place prior to the earthquake, during the process of recovery the local government did not forcibly ask the people to restore every historic building with original materials, additionally there were no legal consequences. This led to some historic buildings being restored with new materials or demolished, even historic spaces were changed. In Zhaohua, although a conservation plan was in place, mainly this plan focused on the preservation of traditional space and did not include emergency management on how to control the historic space and what should be done during a disaster and post disaster.
