After the Lin Shuangwen Rebellion, Xinglong Village Old Town (now Zuoying Old City), originally Fongshan County (equivalent to the administrative center), was completely destroyed. The Qing court moved the county government to the lively Xiapitou Street (now Fongshan). From then on, Xiapitou Street became "New City” while Xinglong Village was called "Old City". Both government officials and the people of Fongshan County migrated between the two locations, forming an interesting "one county two city" phenomenon. Today, Fongshan New Town holds remnants of its former glory that include: Dongbianmen, Pingcheng Fort, Hsunfeng fort, and Chenglan Fort, etc., to commemorate the "one county and two city " era.
002 鳳山／鳳山縣城殘蹟（鳳山新城）
林爽文事件後，原本作為鳳山縣治（相當於行政中心）的興隆莊舊城（今左營舊城）殘破不堪，因此清廷將縣治遷往當時更熱鬧的下埤頭街（今鳳山），此後下埤頭街的縣城稱為「新城」，位處興隆庄的原有城池被稱為「舊城」，鳳山縣的官民曾在這兩座新舊城池間來回遷徙，因此形成「一縣雙城」的有趣現象。今日鳳山新城僅餘留部分殘跡，包括：東便門、平成砲台、訓風砲台、澄瀾砲台等僅供世人懷思，也紀念了那段「一縣雙城」的歲月。
