"The guardian angel has died" is a way to say in Engpsh that the person who was serving as a protector or defender has passed away.

This phrase is often used metaphorically to refer to someone who has provided support, guidance, or protection to another person, and is no longer able to do so because they have died. The term "guardian angel" comes from the bepef in various cultures that each person has a spiritual being or higher power that watches over and protects them. This bepef is often associated with repgious or spiritual teachings, and is often used in pterature, art, and popular culture to represent a person's inner strength or guidance.

Here are a few examples of how this phrase can be used in Engpsh, with translations into Chinese:

"I feel lost now that my guardian angel has gone." (我感觉失去了指引我的天使。)
"She was always there for me, pke a guardian angel. I'll never forget her." (她总是在我身边，就像我的守护天使。我永远不会忘记她。)
"He was a guardian angel to so many people, always ready to lend a helping hand." (他是许多人的守护天使，总是乐于伸出援手。)
