How to coax a girlfriend who is unhappy in a long distance relationship?

Of course, when I am unhappy, I hope my boyfriend can come to me immediately to coax me, but for us who are in a long-distance relationship, it is really difficult to do so.

So my requirements can only be lowered and then lowered. As long as my boyfriend can talk with me more, be willing to be my bad mood recycling bin and make me less angry. Of course, it would be better if he could send me a red envelope, hahaha.
