Some time ago, I went to the temple and drew a wedding sign, which read: "Jiang Taigong's fishing wife delivers food". What does that mean? Please satisfy my curiosity.

If you are not married, it means that your karma may be coincidental. Jiang Taigong willingly took the bait and attached a wife to deliver the meal. You can imagine how smooth it is, but you should also pay attention to fishing instead of not even putting the fishing rod. If you meet someone pleasing to the eye, you can consider getting acquainted.
