Suppose in Shenzhen, some banks have business card printing centers in Shenzhen and some in Shanghai. It takes two weeks from approval to card collection, not to mention the approval process and so on.
Like Guangfa Bank, the business card printing center is in Guangzhou, so the card issuing speed is relatively fast. Like powerful banks, that is, state-owned banks, usually the business card printing center is in Shanghai. All four lines.
