### Chinese: 看好编号下单，古董物品售出不退不换。
### English: Place an order according to the number, and antique items are non-refundable and non-exchangeable when sold.
### Errors: There is a major error at "Place an order according to the number".

### Improved English: Please check the serial number before placing an order, and all products of the antique type cannot be exchanged or refunded once sold.
