Description: You can hit the target every time, describing archery or shooting as flashing. Metaphor is to do things with answers and never fail.

Yang was a famous strategist of Chu State in the Spring and Autumn Period and a famous archer in ancient China. There are some stories about him in Zuo Zhuan and Historical Records. For example:

Once, I attacked Zheng. Chu Gongwang sent troops to help Zheng, and Jin joined forces in Yanling (the so-called "Yanling War"). Yanling (now Henan Province). In the battle, Kim shot his eye. Chu Gongwang hated it, so he asked Yang for two arrows to avenge himself. As a result, Yang shot the gun with only one arrow and returned the other arrow to me.

In Chu Gongwang, there is also a good shooter named Pandang, who can hit the target red heart with every arrow. Yang said to him, "This is not a skill. It is almost enough to shoot willow leaves from a hundred paces away. " Pandang refused, immediately chose three leaves on the willow tree, marked them with numbers, and told Yang to retreat to a hundred paces and shoot them in sequence. Yang shot three arrows in a row, and sure enough, the first arrow hit the No.1 leaf center, the second arrow hit the No.2 leaf center, and the third arrow hit the No.4 leaf center, which was very accurate.

"Historical Records" said: "Chu has Yang, who is good at shooting, but also good at shooting. Go to the willow tree and shoot it with a hundred steps. "

Describe the skill of archery, so it is called "a hundred shots and a hundred hits", also known as "a hundred steps to pierce the Yang". Wang Xuan's "Shooting Classics" said: "Its (arrow target) starts from ten feet, and it hits every shot, adding inches (increasing the distance one by one). As for wearing a hundred steps, it is also a hundred shots. This is a skill. "

Today, people often use this idiom to describe the shooting skills of sharpshooters, and it can also be used to mean that things must be neutralized and things must be achieved.
