Many Buddhist temples and sculptures were built during Wu Zetian's reign.

During the middle ages, Buddhism reached its highest potential under the reign of Empress Wu Zetian of the Tang dynasty, her active role with Buddhism fabricated a perpetual impact on the Chinese dynasty. 
Empress Wu Zetian ordered many Buddhist temples to be built, and sculpture to be created around China. She also gave monks more power and invited scholars to China to spread the Buddhist teachings. Additionally, Empress Wu Zetian created a law that made Buddhism more important than any other belief systems in China.

It has the potential to lead to limits on rights by giving flexibility in making laws.
