I want to know the answer to the following question:
When did Ayurbarwada Buyantu Khan reign?
All the background I'm provided with is that "Rossabi writes that Kublai recognized that in order to rule China, "he had to employ Chinese advisors and officials, yet he could not rely totally on Chinese advisers because he had to maintain a delicate balancing act between ruling the sedentary civilization of China and preserving the cultural identity and values of the Mongols."". Is that enough to answer the question?
