郭臺銘因出生喺板橋慈惠宮，並喺宮內的廂房住咗九年，自認得到媽祖嘅庇佑。郭臺銘都篤信關聖帝君（關帝君、關帝、關公），喺鴻海嘅土城總部內都奉祀關帝神像，曾親自前往山西解州關帝廟迎接關帝軟身神像來臺。郭臺銘曾遭遇胡宗賢炸彈案，不過爆燃物未引燃，虛驚一場。郭臺銘稱炸彈未爆炸係關聖帝君顯神靈。2014年太陽花學運期間，郭臺銘自稱奉關公顯靈指示，協調學運退場。2019年4月17日，郭臺銘到板橋慈惠宮同淡水武聖宮參拜、請示神意，係唔係要參加2020年中華民國總統選舉；郭臺銘表示，媽祖前幾天有託夢，要佢出來為受苦受難嘅老百姓做好事，帶給臺灣和平繁榮，他一定會遵照媽祖指示。
Because Guo Taiming was born in Banqiao Cihui Palace and lived in the wing room of the palace for nine years, he recognized himself as blessed by Mazu. Guo Taiming also firmly believes in Guan Shengdi Jun (Guan Dijun, Guan Di, Guan Gong), and worships the statue of Emperor Guan in the Tucheng headquarters of Hon Hai, and personally went to the Guandi Temple in Jiezhou, Shanxi Province to welcome the statue of Emperor Guan's soft body to Taiwan. Guo Taiming once encountered Hu Zongxian's bomb case, but the explosive materials were not ignited, and there was a false alarm. Guo Taiming said that the bomb did not explode, and it was the Guan Sheng Emperor who showed his spirit. During the 2014 Sunflower Student Movement, Guo Taiming claimed to have been instructed by Guan Gong to coordinate the exit of the student movement. On April 17, 2019, Guo Taiming went to Banqiao Cihui Palace and Tamsui Wusheng Palace to pay homage and ask whether he wanted to participate in the 2020 presidential election of The President of the Republic of China; Guo Taiming said that Mazu had a dream a few days ago to make him come out to do good deeds for the suffering people and bring peace and prosperity to Taiwan, and he will definitely follow Mazu's instructions.
