The meaning of this sentence is: Wait until one day you meet such a person who you find pleasing to both of you. It is like seeing a beautiful rainbow. No matter how beautiful others say it is, you have never seen it. You have to see it with your own eyes. I think it's so beautiful.
This sentence comes from the review written by the famous writer Han Han for the movie "Heartbeat": "Some people live in high-rise buildings, some live in deep ditches, some are bright, some are covered in rust, there are thousands of people in the world, and there are no floating clouds. Go and seek, this person is like a rainbow, you will know there is one when you meet him.”
It is not difficult to understand the meaning of “This person is like a rainbow, you will know there is one when you meet him”. It means that the person is like a brilliant rainbow. , only when you really encounter it can you know how beautiful it is. Although this sentence only has ten words, the praise it expresses for "this person" and the joy of "encountering" it is so strong. It really fits the name of the movie and makes people "heartbeat".
