《宋史·列传·卷四十九》
乾兴年间，王曾由副宰相做会灵观使，曹利用由枢密使兼领景灵宫使，当时宫使与观使重复，皇上下诏确定曹利用的地位在王曾之上。
乾兴中，王曾由次相为会灵观使，利用由枢密使领景灵宫使，时重宫观使，诏利用班曾上，议者非之。
During the Qianxing era, Wang Zeng went from Deputy Prime Minister to Imperial Minister of the Daoist Temple of Spiritual Harmony, and Cao Liyong from Imperial Minister for Military Strategy to Imperial Minister of the Daoist Temple of Spiritual Tranquility. At that time, the Imperial Minister of the Palace and the Imperial Minister of the Temple had overlapping responsibilities, and the emperor issued an edict confirming that Cao Liyong's status was higher than that of Wang Zeng.
