Lian Zhendong, Liu, Lin Dingli, You Mijian and Huang are considered to be the "middle class" of post-war politics in Taiwan Province Province (politicians who went during Japanese rule and returned to Taiwan Province Province after World War II). In Taiwan Province writer Wu's posthumous work "Forsythia Taiwan Province Province", Lian Zhendong was called a "sinister counselor". Lian Zhendong has successively served as director of construction, director of civil affairs, minister of interior, senior minister of presidential office and national policy adviser in Taiwan Province Province, laying a solid foundation for the party and government circles. The political relationship between Lian Zhendong and Lian Zhendong in the past dynasties has cultivated a huge vein of politics and business, which can make his son Lien Chan invincible in the political and business circles. Lian Zhendong personally taught Lien Chan the key to being an official: "Just like riding a bicycle, your head should be in the same place and your feet should be on it." . Moreover, Lian Zhendong's role in the takeover of Taiwan Province Province and the February 28th incident, as well as the huge property left by Lian Zhendong to Lien Chan, have become the controversial points of Lian Zhendong.
