Analysis:
Yes, anything meaningful can be sent.
There is a story that the mountain god gave the goddess a mirror as a gift, but it was later broken, and the fragments fell into Jiuzhaigou, turning it into 106 lakes of all sizes. This is the only lake in Jiuzhaigou called "Pool"-Colorful Pool. A beautiful story.
"Duke of Zhou" said that dreaming of giving someone a mirror as a birthday present indicates that something good will happen, and it may not be long before you can drink someone else's wedding banquet.
Believe it or not has little to do with this. The important thing is that the giver and receiver get the message and are happy.
