What does my girlfriend mean when she says I am an old man in Changbai Mountain?

Old ginseng in Changbai Mountain-the older you are, the more valuable you are!

This means that the older you are, the more valuable you are.

This means that you are not shallow in education and experience, but you are rich in knowledge and always develop complex things logically; Although "mature", it contains advanced nutrients.

I'm not lost after many important events. Self-mature and steady. This is the point of praise.

If you grew up in an ordinary family, this evaluation is not low.

This evaluation includes the factor of recognition.
