Qiganli (South) was named after the flagpole stones in front of the gate. There are three remaining courtyards in Qiganli (South) including a foyer, a main hall, a front yard, a principal hall and a back yard on the central axis. The front yard is flanked by a two-storey Xiangfang on the left and right, while the two-storey principal hall is three rooms wide, with its gable walls now in some disrepair although in general, the house is still relatively intact. The building area amounts to 2,419.36 square metres. The original flagpole was struck by lightning in 1953 and has now collapsed and been placed across the gate. The other two stone flagpoles were used as water-powered pestles to pound rice during the Cultural Revolution.

According to the research of the elders Wu Ruzhi, Wu Xujian, Wu Xianggui the houses in Qiganli (South) were built by Wu Shuzhi (1802-1848), the 31st generation of the Wu family, who had five sons, Xijun, Xilun, Xiewei, Xixiu and Xichun. Wu Xichun (1842-1903), a tribute student (see definition below), was the youngest son of Wu Shuzhi. According to the genealogy of the Wu family, Wu Xiaozhou was ordered to place a pair of flag poles at the entrance to one of the houses in Qiganliin 1897 At the age of 55 he was honored as Sui Jinshi, and there was a plaque of Sui Gong (岁贡)placed in front of the hall. [Note: Sui jinshi岁进士, annual presented scholar, should not be confused with the Jinshi of the imperial examination. The term is an unofficial reference to tribute students coming from local Confucian Schools that existed throughout the Empire who were promoted every year to the National University, as opposed to the students of the Yi Xiangsheng 邑庠生(xiucai)or Fu Linsheng (best qualified xiucai who were paid stipends). It is a kind of treatment to encourage young people to study and not a formal scholarly honor or official rank. It can be written in “private” genealogies and inscriptions, but has no official status.]
