I know about that book......still, the Mongols took inspiration from that book and the Chinese took inspiration from the Mongols. Mongols were the first ones to popularize paper currency around the world, which is why I hinted towards the Chinese currency being called "Yuan". I know your currency is also called Renminbi...As I already said, Yuan the name of the dynasty was derived from an ancient chinese book "易经“, and the name of the currency yuan can only be dated back a hundred years ago, late Qing-Republic of China.
You seems to be confident about your knowdeldge on Chinese subjects but I recommended you to focus on some more reliable books/articles.
anyway, you don't have to replied me, let's stick to topic which is about Mongols..
