Urine bubble refers to pig urine bubble. Although it looks quite big, it actually has no weight. Although it is quite small, it can hold down the weight of 1000 kilograms. To sum up, these two seemingly opposite words express the same meaning: don't judge a book by its cover.
If you think about these two sentences carefully, they really contain truth. Think about the people and things we meet in life. There are many people screaming, seemingly eloquent. If you really encounter something, you will be arrogant enough to put out the fire. They can't come up with any real skills, so they can only be slapped in the face.
And those who don't look very impressive on weekdays, never make public, and keep a low profile can solve problems quickly and are fatal. Just like those sweeping monk in the martial arts novels, although he looks like an ordinary little old man, he is actually a peerless master who is invincible in the world.
For example, in Everything is Fine, the three sons and daughters of the Su family, the eldest brother and the second son always talk big, as if they have much skill. If they really can't fart an old Dalian, the second child will be bluffing. Isn't Su Mingyu the one who can really solve the problem?
So, you really can't judge a book by its cover. You can't look at what a person looks like on the surface, but at his essence and what he can really do. Each of us should always keep our roots, and don't forget your initiative. Those flashy superficial efforts are really meaningless. In addition, we should pay more attention to the details of some things. Although some details are small, they can have a great impact on the whole, determine the final direction of things, grasp the whole without ignoring some parts.
