This opera is based on historical facts and has artistically represented the stories of China-Japan cultural exchange through the ages.
In 742 AD (the first year of Tianbao’s reign in the Tang Dynasty), at Japanese monks’ invitation, eminent monk Jianzhen took sea-voyage eastward to Japan for six times successively, through innumerable trials and hardships, he finally reached Japan in 754 AD. Among his companions, there were people having knowledge of art, medicine, and skillful craftsmen. He brought a large number of books and cultural objects to Japan, and painstakingly propagated the cultural achievements of the Dang Dynasty. Up to this day, the altar lamps in Daming Temple in Yangzhou, China and Toshodai Temple in Japan reflect with each other with warmth and peace light in distance.
