Comparison between SSEC and A50:

One can see that, it's better to buy A50 index or 2823.HK to chase the crazy China mainland market.

Comparison among MXCN, HSCEI and FXC25 (FXI):

They are similar but not precisely the same.  MSCI China index is similar with HSCEI.

If we put HSI, HSCEI, A50, and FXI together, one can see that in term of volatility, SSEC~A50 > HSCEI~FXC25~MXCN > HSI.

Conclusion:

• China mainland market: 2823 in HK exchange, or CAF on US market;  Check $SSEC or $FTX;
• China H-shares on HK market: FXI on US market; Check $FXT or $HSCEI;
• Broad HK market: 2800 on HK market.  Is it really attractive since we can trade 2823 or CAF?
