The rural credit cooperatives in Tianjin have been restructured and called Tianjin Rural Commercial Bank. It seems that there is also a coastal rural commercial bank. If you remit money, you don't need to remit it to the rural credit cooperatives. You can remit money across banks, and the handling fee is not much different from that in banks. You can also open a card in Tianjin Rural Commercial Bank and remit money through the channel of Rural Credit Bank, which will be cheaper.
Please adopt it.
