First, I don't know how you added the length. Generally speaking, the store will not simply add an extra necklace to your original necklace and then charge you a dollar, unless it is a small gold shop and you are familiar with the boss. Because the gold shop earns manual fees, your chain is charged the overall processing fee, but it is not cost-effective to lengthen it. It is better to change the style directly, and the price is the same anyway.

Second, if you type again, it is recommended to go directly to the gold shop to change the style and pay the manual fee. Because if you go to Xiaojindian to play, you will basically play once less. The impure gold is, the less it is.
