Luo Qiao walked away, but the people she left behind were all exchanging glances, wondering what Luo Qiao had just said. Some of them couldn't understand the meaning of her words at all.
A Zhang Family man looked towards Zhang Yuewen, "Yuewen, you're well-educated. What did Luo Qiao mean just now? Explain it to your uncle."
Zhang Yuewen didn't want to say anything at first, but seeing that his grandfather was also looking at him, he spoke up, "Luo Qiao means that we now live in a society ruled by law. If you do something wrong, it must be dealt with according to the law, not as in the old society when the clan had the final say.
The phrase 'Do not do unto others what you do not want done unto yourself' means that you should not impose on others what you would not want for yourself. You all understand the last sentence she said; I don't need to explain it."
