As a Chinese citizen I once traveled to Taiwan without the special permit, the immigration officers were really mad on that.
As others have said, you cannot do this.
You will almost certainly get caught at some stage, and there have been data points of passengers getting physically taken off flights - even after they have boarded - when they have tried this. You then get questioned and possibly fined.
You may not be 'arrested' but you will be detained.
