Probably the least sophisticated way is to buy shares in an inverse ETF. There are a couple bear market ETFs that target Chinese indexes (FXP and CZI). (I'm not endorsing anything here; please understand whatever you invest in before doing so.)

Don't buy any inverse ETFs until you understand the "inverse ETF decay" problem well. Serious stuff.

This really cannot be said enough. I thought I had figured out a way to arbitrage the oil market sometime last year. Luckily I decided to "make the trades on paper" and see how it turned out before actually putting down ten grand. The devil is in the details, of course, and after watching what happened and fully reading the prospectus of the inverse oil ETF I realized what happened. Always READ THE PROSPECTUS if you are going to be using ETFs or anything else exotic. Again: READ. THE. PROSPECTUS.
