Have a formal company qualification and can handle it without criminal behavior. The company applied for 3a credit rating certification before, which was completed on a small program called Run Zheng Tong. Pretty fast, I received it the next day. The boss said that the price seems to be better than the on-site discount, and both Alipay and WeChat can find it. After entering Runzhengtong, I chose AAA certification. If you still don't understand, you can look it up.
