Here's some grown-up advice: don't invest in property or shares – they're dull. Instead, head to Beijing on holiday and swing by one of their walnut shops, where the healthy food items are selling for tens of thousands of dollars EACH (and reselling for double the price just a year later). Wealthy Chinese men like to stroke their nuts with their hands (wahay!) – it's to stimulate blood flow through the body, and bring luck in life, apparently.
