What if the Longmen Grottoes are fully booked?

Longmen Grottoes are full, so we can't make an appointment. We'll just have to make another appointment.

Longmen Grottoes are the only royal grottoes in the world, and most of them were built by royal nobles. After the news of the Lushena Buddha carved by Wu Zetian according to her appearance and manners and the construction of a paradise in Luo Yang Palace was introduced to Japan, Emperor Shengwu made a vow of "building for me" and established Dongda Temple in Nara.
