@@栗原寛司-h2n 5000-year history of China is a widely accepted opinion in China. The earliest accurate history(to year) started from 841BC(the first year of republic“共和元年”) , the earliest dynasty with solid proof is Shang(商), about 3500 years ago, and before Shang is Xia, which now lacks archaeological evidence. But it’s true that there’s multiple advanced civilizations with cities and palaces before Shang, just don’t know which is Xia, the main one.
