The idiom "Crouching Tiger, Hidden Dragon" comes from China's ancient novel "The Legend of the Swordsman in Yongzheng", which was later adapted into a classic martial arts film. Many characters in the film play tigers with hidden strength and dragons with soaring strength. This idiom is now used to describe people who are unknown and waiting for opportunities to break out. After success, they will become stronger and more mysterious than before. This idiom makes people realize that internal strength and strategy can determine a person's fate more than external image.
The tiger is a brave and fierce animal. It has the ability to beat many other animals. In China culture, the tiger is a very special animal, which is associated with special qualities. In this idiom, "tiger" represents the strength, courage and wisdom of an individual or a team. The usage of this idiom is "getting ready", just like a crouching tiger waiting for its prey. We can use this idiom to describe those who don't make a sound. They don't talk much, but they are full of strength and wisdom. Once they start, they will beat their opponents mercilessly.
