At present, the safest way is to buy books from Amazon, Dangdang, JD.COM and Midway Online. Although I can't guarantee the authenticity of 100%, I have bought many books and found no problems. Taobao Tmall has many imitations.
As for the general history of China, I suggest reading the books published by Mr. Lv Simian and Shanghai Ancient Books Publishing House, which are traditional and horizontal, and the paper is very general, but the reputation of ancient times lies there, and their books are still carefully proofread, that is to say, there are fewer mistakes and omissions.
Mr. Lu's general history of China, especially the first half of cultural history, is quite well written. This is the textbook he wrote for students. Looking at the development of China's history from the perspective of cultural system, you would never have thought that there were so many things before you read them.
In addition, Mr. Qian Mu's Outline of National History is also worth recommending.
However, these two gentlemen were born in the Republic of China, and their works are a bit classical. Just get used to it.
