Always interesting to read history of all times. It's great to see how a chaotic era and its different geopolitical landscape can be treated in such a careful way! I think it's crucial to a historian in 21st century to always having the context before and after the interesting period. Dr. Li manages to explain the "historical exit" towards Song Dynasty with fruitful discussions on various models of local developments and centre-locality relationships. It may seem crazy, but I think late-Tang dynasty can be a good background for Gaming design, as many have been doing on the Three Kingdoms!
