There's a proposal being voted on by the #bitshares committee that will modify the so-called settlement "guarantee". The proposal currently has a majority of votes, and if things stay that way, it will take effect on June 21, which means that you can no longer settle your bitCNY for the value of 1 CNY, but only for 0.99 CNY after that date.

If you are against the proposal, you can vote indirectly, by no longer voting for those committee members who are in favour of the proposal.
