Why are Sell Bids created after I have won shares at a Fusu IDO Auction?

For 50% of all winning bids at a Fusu IDO Auction, Sell Bids are automatically created at a 10% premium to the initial share price. These bids are valid for 7 days.

This was introduced in order to guarantee some liquidity and access to shares to "late comers" in the market.
