[3] In 1974, the Ministry of the Interior founded the Jūngōngjiào Fúlì Zhōngxīn (軍公教福利中心), a supermarket with cheaper prices and no sales tax whose access is restricted to military, civil servants, and educators.

[8][9] During the controversy, the company was privatized and headed by Lin Ming-Hsiung, founder of Yuanlih Construction (元利建設); its 66 stores were rebranded as PX Mart and were opened to the public.

[10][11] Under new leadership, Lin aggressively increased their market share through mergers with other chains, acquiring Yanglianshe (楊聯社) in 2004, the stores in Taiwan owned by the Japanese chain Summit (supermarket) [ja] in 2006, and the stores operated by Taipei Agricultural Products Marketing Corporation [zh] in 2007.

[16] The same year, PX Mart opened two warehouses in Guanyin, Taoyuan and Gangshan, Kaohsiung,[17] and became the first overseas member of the All Japan Supermarket Association [ja].

[1] PX Mart operates three warehouses, located in Guanyin, Taoyuan; Wuqi, Taichung; and Gangshan, Kaohsiung.
