In 724, at Zhang's suggestion, Emperor Xuanzong began to prepare a grand ceremony (known as Fengshan () to offer sacrifices to heaven and earth at Mount Tai—despite opposition from fellow chancellor Yuan Qianyao, which began discord between Zhang and Yuan. Emperor Xuanzong carried out the ceremony at 725—and the ceremony caused much resentment toward Zhang, as, at Zhang's recommendations, a number of officials at the legislative and examination bureaus participated in the ceremony and were promoted after the ceremony, but other officials were not awarded, and neither were the soldiers who attended to Emperor Xuanzong during the ceremony. Zhang himself was given the additional title of You Chengxiang (), one of the heads of the executive bureau.
