### Chinese: 看好编号下单，古董物品售出不退不换。
### English: We are optimistic about the number of orders, and antique items will not be returned or exchanged when they are <v>sold</v>
### Errors: There is a minor fluency/punctuation error at "sold" 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.
