XinYi Public Assembly Hall was Si-Si Nan Cun. It was the first military dependents' village which offered a place to stay for military dependents of LianQing Armory No 44. They were moved from QingDao , China in 1948. Because of the location they were moved from, most of them were from ShanDong and HeNan . The village was a warehouse when the time Japanese seized Taiwan . After emptied the warehouse, all the workers and their dependents lived in the warehouse. Each room takes about 11 square meters. At the beginning, all the workers thought they will go back to their hometown as soon as possible so they divided the room with clothes. However, the population was growing up so they extended the warehouse. Then, this area became new hometown for the workers and their dependents for more than fifty years.

Most residents in Si-Si Nan Cun are technicians with low salary level. Hence, some of the fathers in this village had to ride Pedi-cabs as part time works. Mothers will do some washing jobs or some handicrafts or selling breakfast as subsidiary. Since working in an armory is dangerous, there were quite a lot of widows. They need to raise their children by themselves. Because of financial problem, the typical jobs of their children are soldiers or apprentices; some of them cannot afford their children's education, and they send their children into orphanages.

All the power supply came from the armory in the village during that time. The armory controlled the timing of using power in the village; hence, during that time, the second generation grew up in that circumstance. A lot of people stand close to power polls and tried to study for their advanced examine. You can image how hard it is to live in this environment during that time.

In 2001, under the calls of people in the intellectual circles, they sat up “XinYi Public Assembly Hall” and announced Si-Si Nan Cun as a historical building. Also, they assigned four of the buildings to be conserved for historical testimony.
