Peeping a leopard through a tube (guǎn zhōng kuī bào)

Explanation: Looking at a leopard through a small hole in a bamboo tube, you can only see a stripe on the leopard's body. Metaphor only sees part of something. Sometimes it can be used together with a glimpse, which is a metaphor for seeing only part of something, meaning that what you see is incomplete or only a little bit gained.

Origin from Liu Yiqing's "Shishuo Xinyu·Fangzheng" of the Southern Dynasties and Song Dynasty: "This man also peeks into the leopard and sees something from time to time."

Allusions

Liu Yiqing of the Southern Song Dynasty's "Shishuoxinyu·Fangzheng": "When Prince Jing was a few years old, he tried to see the disciples playing Pu, and saw the winner, because he said: ' Nan Feng Bu Jing. The disciples looked down upon his son and said, "This man also looks at a leopard through a pipe and sees a spot." It means that when you look at a leopard through a pipe, you only see a stripe on its body.

Translation: Wang Xianzhi is the last son of Wang Xizhi, a famous calligrapher in the Eastern Jin Dynasty. He is very smart. When he grew up, he also became a famous calligrapher and was known as the "Two Kings" together with his father.

One day, several of his father's students were playing cards. Xianzhi, who was watching from the sidelines, was actually able to give advice to others and speak a few words of knowledge. Unexpectedly, the students all laughed at him and said: "This man is also able to catch a glimpse of the leopard and see something!"

When Xianzhi saw them talking about him like this, he couldn't help being furious and said: "I am ashamed of Xun Fengqian from afar, and I am ashamed of Liu from afar!" It’s really long.” He threw off his sleeves and walked away.

The two idioms "Peeping a leopard in a tube" and "Going away" are all derived from this.

There are two completely different understandings of "seeing a leopard in a tube": one is a complimentary meaning, which means that people can infer the whole picture of something from a part of it observed. To literally understand "peeping at a leopard through a tube" means to see a leopard through the line of sight through a "bamboo tube". Since the line of sight is limited by the area of ??the circular hole in the "bamboo tube", the "whole leopard" cannot be seen, only the leopard can be seen. The spotted pattern on the body is very characteristic of a leopard, so it is inferred that this is a leopard. This kind of thinking is extremely wise. "You can see the whole leopard from one spot", "See the world from a grain of sand", "Understand the ocean from a drop of water". These words are often used to praise those smart people who see the big from the small and understand the big principles through small things.

But if we think backwards about this sentence, we will immediately find that it is full of loopholes. "If you look at a leopard through a tube, you can see a speck." So, is it true that anyone who can see "a speck" is a leopard? No! The markings on the sika deer are by no means inferior to those of the leopard. Therefore, the same "seeing a leopard through a tube" might lead to an unjust case of "calling a deer a leopard"!
