What is the relationship between Wu Zetian and Wei Zicheng?

In the first year of God's will (AD 690), Wu Zetian ascended the throne in Wei Zi and proclaimed himself emperor, with its capital in Shen Du; Weizi Town is an important place for the Empress to participate in politics, worship Buddha and live. The buildings built by Wu Zetian in Weizi Town, such as Tang Ming, Paradise and Jixian Hall, formed a magnificent skyline, which made the three-dimensional outline and style of Weizi Town more magnificent.
