Starting with the words "Shang and Zhi", this is the highest example of embedded characters, and I am willing to do it.
Into the room, Li Xiude people gold in hand;

Joint analysis
On the surface, "entering the classroom" means that teachers and students enter the classroom, and on the deeper level, it means learning cultural knowledge into a high level;
"Holding gold" is a metaphor for learning true knowledge, and its meaning comes from "the book has its own golden house".
The "Yu Ying God" from the first book "Holding Gold" is also a metaphor for learning true knowledge, but further, it has "real ability" and "real talent and practical learning".
Starting with metaphor, the whole couplet summarizes the purpose of kindergarten (garden style) and incorporates deep hopes and expectations for children (students), which is self-evident.
