The new edition of History of Rome is quite different from the previous edition. This mainly refers to two volumes, covering the first 500 years of Roman countries. At the beginning of real history, it decided and arranged the content and form of performance for its own reasons. In the early stage, because there is no boundary in the study of historical sources, it is difficult to determine the time of historical materials and there is no connection between them. The difficulty encountered by historians is that it is difficult for him to satisfy others, and of course it is difficult for him to satisfy himself. Although the author of this book has worked hard to overcome these difficulties in research and expression, there are still many things to be done and many places to be revised before presenting this book to the public. A series of new studies, such as the status of Roman subjects in national law and the development of creative arts and plastic arts, have been included in this edition according to their achievements. In addition, many small loopholes have been filled, and the style of writing has generally been changed to be more vivid, richer in content and clearer in overall layout. In addition, in the third volume, the internal relations of Roman civil society during the Punic War are not only outlined as in the first edition, but also described in detail according to the importance and arduousness of the matter. An impartial judge, perhaps the first person who has undertaken a similar task, will know how to explain that this compensation is necessary and ask for forgiveness.

In any case, the author gratefully admits that the public's criticism did not emphasize the obvious loopholes and shortcomings of this book. On the contrary, appreciation and opposition were directed at those parts that have come to an end or have been completed. Besides, the author has tried his best to arrange the book more appropriately in appearance. Varo's Roman calendar remains in the text; The symbol in the blank refers to the corresponding year BC. When comparing the years, 1 year in Rome is equivalent to 753 BC and 6 or 4 years in Olympia. Although considering the different start of a year, the solar year in Rome starts in March of 1 year, and in Greece it starts in July of 1 year. According to more accurate calculations, the two years in Rome are equivalent to the last ten months in 753 BC and the first two months in 752 BC, as well as the last four months in June and March in Olympia and the first eight months in June and April in Olympia. Roman currency and Greek currency are exchanged in the following ways. In Attica, the Roman pound was considered equivalent to Cestes, dinars and drachmas. All currencies above 100 dinars are based on the current gold value of the corresponding weight, and all currencies below 100 dinars are based on the current silver value of the corresponding weight, so one pound of Roman currency (= 327.45g) is equal to 4,000 Ceste. Tarun, Prussia and Dinar are converted into 7 Prussian Groshen according to the value of silver. The map of Kiepert attached to the first volume shows the history of Italy more clearly, which is better than narration. A summary of the contents marked in the margin is convenient for readers to have a general understanding. The alphabetical list will be attached to the third volume, because the author has other responsibilities and can't finish the work as soon as he hopes.
