Viewing Aid
1) The map is oriented North
2) The bulk of the map is centred on mainland China. Korea and Japa and clearly visible as are the islands of the South China Sea
3) On the far left are the Arabian Peninsula and a rather diminished Africa
4) To be honest, the depiction of Europe is a bit of a mess
