Hello I want to find male or female, don't mind what genre that go back to the past or in 1900 year something.
I've read a bunch of books that do this. Respectively, they're start in 1886 Vienna, 1895 Beijing, and 1903 London. These are all untranslated Chinese novels but I'll give recommendations if that's still okay.
重生之大科学家 This story is about a nuclear physicist who transmigrates to Beijing shortly before the Boxer Rebellion. It is largely about science and education but politics and war also play a role. 回到英国当大亨 The protagonist transmigrates to London in 1903, and the story starts off as a recreation of the film "the Million Pound Note" wherein he's given the bank note in question but can't actually spend it. This story is largely about business and finance. I don't bother listing the Vienna one because I don't think it's that good. And if you're actually interested, you might as well read "Holy Roman Empire" instead. Both books are by the same writer, they both start in Vienna, they're both about monarchs (Ferdinand I vs. Franz Joseph I) and this book is probably better than the other one.
