This idiom expresses the principle of treating others with the same consideration and respect that one would desire for oneself.
In my work, I always try my best to help my colleagues, because I believe in 'do as you would be done by'.
When interacting with others, remember the principle of 'do as you would be done by'; it can help to build better relationships.
If we all followed the principle of 'do as you would be done by,' the world would be a much better place.
