 Instead, in the center building of the Temple of Heaven, in a structure called the "Imperial Vault of Heaven", a "spirit tablet" (, shénwèi) inscribed with the name of Shangdi is stored on the throne, "Huangtian Shangdi" ().During an annual sacrifice, the emperor would carry these tablets to the north part of the Temple of Heaven, a place called the "Prayer Hall For Good Harvests", and place them on that throne.It was during Ming and Qing dynasty, when Roman Catholicism was introduced by Jesuit Priest Matteo Ricci, that the idea of "Shangdi" started to be applied to the Christian conception of God.
