Idiom: Peeping a leopard through a tube
Pinyin: 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 . It is a metaphor for seeing only part of something, which means that what you see is incomplete or only a little bit gained.
Idiom story:
Wang Xianzhi, the son of the famous calligrapher Wang Xizhi of the Jin Dynasty, was famous as a boy.
Once, he watched his disciples playing dice and found that one of them was about to lose. He said, "The wind in the south is not strong." The disciples laughed and said, "This child looks like he is watching from a bamboo tube." A leopard can actually see a little bit of it." Wang Xianzhi said angrily: "Don't underestimate people! I am ashamed to be inferior to Xun Fengqian (Xun Can, a man of the Wei Dynasty during the Three Kingdoms, who was noble and talented) from afar; Yes, I am ashamed to be inferior to Liu Zhenchang (Liu Xun, Wang Xizhi's friend)." After saying this, he walked away.
Later, Wang Xianzhi became a famous calligrapher, as famous as his father Wang Xizhi, and was called the "Two Kings" by later generations.
