Literally, it has no deep meaning, and it is not from allusions. I'm afraid only she knows what this means, but I can teach you a way to connect you with her or her "orange". You change your signature to: "I'm going to buy some oranges, so you stay where you are." "(This is the back of Zhu Ziqing, and it is also a hot topic on the Internet now. The specific meaning can be checked online. ) Next, you can chat with girls and say, Hey? I just read your signature, which is very similar to mine. You sell oranges and I buy oranges, haha. If she asks you what this means, you can also make her say it's from that article, or say, I'm your father or something, just kidding. If she says she sells oranges and you buy oranges, you can also understand it as the same, oranges in the south and oranges in the north, oranges in the south and oranges in the north. Anyway, you can talk together and talk about a lot of life, study, work, hobbies and so on. Let's go I hope I can help you.
