The next sentence of "Flowers are silent, but the wind understands" is: "Some people come and go, some people are near and far away." It means: Although the flowers cannot speak, the wind can. I understand what he means, some people come and some people leave, some people feel closer and some people feel alienated.
From "Sitting Temporarily" by Jia Pingwa: In late autumn, the flowers are silent, but the wind understands. Some people come and go, some people are near and far away. You see, it’s autumn again in a hurry. The years are countless, and old friends don’t know the beginning. However, sitting in this world for a while will have to go through thousands of vicissitudes of life.
This passage expresses that the years are changing, and the old friends are also changing, and the old friends are no longer the same as when they first met, and have long since changed.
