sometimes credit card sends you checks.  you can use it to write a check.  Or take money out from ATM.  However, you should look at your credit card statements.  The interest rate for cash out is very high.  Some can be more than 20%.

打电话问你的信用卡公司看有没有balance transfer 的offer
或者看看有没有银行寄给你0%的offer
有些offer可以直接把钱打到你的账户
一般手续费是3% 有的有定Max @$70
先去掏掏信箱看有没有Offer 先咯~~
具体手续每个银行不同
