What is Tiaoda Village, Zero Exchange Village and how many regional gangs are there?

Banks whose business is similar to remittance and transfer banks but with less capital are not eligible to join remittance and transfer associations, which are called selection and operation banks. The collection and settlement of bills payable in the pick-up and release village need to be entrusted to the remittance village. Retail bank, also known as retail bank, mainly deals in sporadic exchange, which is the smallest of all kinds of banks. Due to the different backgrounds of investors and managers, Shanghai banks have formed regional gangs. There are nine gangs in Shanghai, Shaoxing Gang, Ningbo Gang, Suzhou Gang, Songjiang Gang, Zhejiang Nanxun Gang and Zhenyang Gang. Among them, Ningbo gang and Shaoxing gang are more powerful, referred to as Ningshao gang for short.
