His previous work "History of Asia" is a classic in the field of world history research. It is one of the required reference books when I take the doctoral exam.
I've seen the original English version of History of East Asia, which is very good. It has been reprinted many times in the United States, but the Chinese version was introduced late in China.
At present, there are few works on East Asian history, which should be the best. The history of Japan, North Korea, South Korea, Vietnam, Laos, Myanmar, Cambodia and Thailand are all involved.
I recommend you to read it.
