Starting with the later Han period (25 to 220), there are references to a large civilisation far to the west from China in the Chinese historical records. This civilisation is called Da Qin and has been identified as being either Rome, the Roman Empire or the Roman eastern provinces.

The annalist makes quite fantastic statements about this civilisation, e.g. "their kings are not permanent", and the name of the king of Da Qin in the year 166 was "Andun".

Now, guess what happens if Roman time is offset (i.e. conventionally dated too old) by 232 years. Do the fantastic statements make any sense? Read more about it here.
