Ludian County is located between 568 m to 3356 m above sea level in Zhaotong Prefecture, Northeast Yunnan. Its total area is 1519 square kilometers, of which 87.9% is mountains and valleys. Such terrain makes transportation inconvenient and impedes the development of the area. Lidian has a low latitude upland monsoon climate. There is no significant temperature difference between the four seasons. The annual average temperature is 12.1 ℃ and annual average rainfall is 923.5mm. In 2012, there are 435,000 people in Ludian, of which 89,000 people (about 20.5%) are 13 ethnic minority groups including Hui, Yi and Miao.

After earthquake, the villagers have lost confidence in traditional rammed-earth buildings. They are eager to have their houses which are anti-seismic, cheap and comfortable. In the collaboration with Professor Bai, Faculty of Architecture and City Planning of Kunming University of Science and Technology, our team has launched a Village Rebuilding Assistance Programme in Guangming Village since Oct. Its aim was to design an anti-seismic village house of rammed earth with traditional features at a low cost, but at the same time, with enhanced and comfortable living environment. In addition to rebuilding, we also wish to provide a demonstration for the local government to formulate reconstruction strategies.
