### Chinese: 看好编号下单，古董物品售出不退不换。
### English: Optimistic about the number to place an order, antique items sold are non-refundable and non-<v>exchangeable</v>.
### Errors: There is a minor style/awkward error at "exchangeable" within <v></v>.

### 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.
