Question

What religion flourished under the Tang? Why?

Answer 1

I believe it was Buddhism.

Explanation:

When Wu Zetian was in reign, she legitimized her power by actively supporting Buddhism. She ordered for the creation of many visual representations of Buddha. There were many spectacular stone temples in Longmen Grottoes. In the largest cave of Longmen Grottoes, she built a large statue called Grand Vairocana Buddha in her own image. In this day, Longmen Grottoes contains many of Buddha statues.
