Called “Foreign Soldier’s Tower” in Japanese military documents, each of the four villages was provided with one or two such towers; they were used as an access entrance of the barrack guards. The house near the lookout of Jian Guo Village-I’s Entrance was number 1 of Village-I; in the past it was the Japanese guard house collocating with the lookout. In the early years after the War, the lookout was still in use, a military post for the national military, but the guard house became a general residence for military dependents after the War; it was called Village Chief’s Resident since one of Village Chiefs had lived in it. It is today used as “Jian Guo Village Renewal Association.”
