Talking about coins found in Chinese soil.
One of my best friends (Dutch like me) is married to a Canadian girl (from Toronto) of Chinese origin. Her father who migrated to Canada told them that in their old family shack in China they had buried some gold. I think they even looked for it when they visited China in the eighties.
To be honest, I do not remember the details, since he told me this some 20 years ago, but it just reminds me that gold has always been a very important way of saving for the Chinese and that will not be different today.
