After Xiang Yu entered Xianyang, he said, "Being rich without returning is like walking at night." . How to understand and evaluate what he said at this time?

I have limited knowledge of history, and I hope my brother will correct me if I make a mistake.

The historical background of this sentence is about this. After Xiang Yu's army invaded Qin Dou, it plundered a lot of gold and silver treasures, and then prepared to go back to their hometown to enjoy them. His counselor advised him not to do so, and he should concentrate on competing with Liu Bang for the world. Xiang Yu said the above sentence to his counselor, to the effect that if you don't go back to your hometown after you get rich (I think it can also be extended to show off and not enjoy), it's like wearing good clothes and walking at night (brocade can be understood as wearing brocade), who will know? This is literal translation, and there are many extended meanings. Different people have different opinions. Later, there was an idiom called "returning home with clothes on", which was just the opposite of the above meaning.
