My Guangfa credit card received an electronic bill, which was filled out by Netease. I forgot how it was set up before.
Open your Netease mailbox and click "Settings" in the upper right corner of the webpage; Then click "White List Settings"; Fill in the "sender's email address" in "Add to White List" of "White List Settings" (that is, the email address that Guangfa Credit Card sends you an electronic bill), and click the "Add" button, and you're done.
