As for novels, there are many scattered books and materials in Okita Souji Union Station, and you can also get them from people there, which is more efficient. There are some translations of The Record of Blood Wind by the newly elected group in Ryotaro Shiba Bar. The dragon horse Sakamoto of Sima and the burning sword are also closing scenes, but they are all in Japanese! There is basically no Chinese version, and the translation in Taiwan Province Province is too old.
If you don't know Japanese, I suggest watching Dahe Opera. The new electoral college in 2004 and the local chicken in 2008 are at the end of the curtain, which is easy to find. A long time ago, there was a 4-episode series about Ryoma Sakamoto (named Ryoma Sakamoto), but it was up to rp to find it.
Another suggestion is to give you a website: Japanese Ancient History Forum, in which the Tokugawa family has a special area with many people and complete information, which is quite real.
