As the queen, Gu Zitong first dealt with Concubine Li's birthday ceremony, and then dealt with the arrival of Beimo Princess Anaya. She sensed Anaya was abnormal and teamed up with Pei Jin to reveal that her dancing was unorthodox, that she was pregnant, and that she was related to the remnants of the old royal court, and sent Anaya to the temple. Later, her uncle Gu Bingwen rebelled, and she set up a trap with the emperor to capture Gu Dang with the help of Pei Jin. Eventually she was canonized as Queen Regent to assist the new emperor. During the process, she kept in mind her mother's advice "don't get emotional", calmly laid out the plan, kept a distance when facing Pei Jin's confession, and became the regent with sole power.
