1. Full exchange: 1. of 3/4 is damaged, and the remaining part is above the level of 3/4. Although the 2. of the Chinese fir is broken, the pieces can match.

Three, no exchange: 1., fire, smoke, water, oil, and dye coupons, which can not be identified by 1/2; and 2. of them are not enough for the rest of the year; 3. of them are pieced together to form a piece of paper which can not be anastomosed; and 4. of them are damaged.

If the damaged bank is damaged, the bank will not be redeemed if it is suitable for the first and second regulations, but intentionally damages the suspect.

It is difficult to identify the damaged tickets for special circumstances, such as floods, fires, etc., which are very difficult to identify. The actual amount of exchange that has been identified is often different from the amount they have applied. In order to avoid future disputes, banks are required to exchange vouchers for special circumstances, in addition to the proof issued by the local judicial organs, and also to fill in the "application for the exchange of damaged tickets", and the amount to be exchanged must also be signed by the holder in person.
