An ancient saying goes, "You can know the beginning by seeing the small things, you can know the end by seeing the ends." It means that you can know the degree of development by seeing the small signs of something.

Source: From "Han Feizi·Shuo Lin Shang 22". Zhou used the elephant chopsticks and the chopsticks were fearful. He thought that the elephant chopsticks would not be able to hold the soup in the earthen bowl, so he would definitely use the rhinoceros jade cup. If the clothes are short and brown and the house is under the moats, then he will have nine layers of brocade clothes and a high platform and a wide room. If you call it this and seek it, then the world will not be enough. The sage sees the small to know the beginning, and sees the end to know the end. Therefore, he is frightened when he sees the chopsticks, and knows the shortcomings of the world.
