(a) the arrow is on the string
At the end of the Eastern Han Dynasty, warlords all over the country often waged wars for territory. Under Yuan Shao, a warlord in Hebei Province, there was a gifted scholar named Chen Lin who was in charge of paperwork. At that time, another warlord, Cao Cao's power grew rapidly, and the threat to Yuan Shao was growing, so Yuan Shao decided to crusade against Cao Cao.
One day, Yuan Shao called Chen Lin and asked him to write an article denouncing Cao Cao. So, Chen Lin drafted an article according to Yuan Shao's meaning, called "For Yuan Shao, Bayuzhou". In this article, Chen Lin not only detailed the crimes of Cao Cao himself, but also insulted Cao Cao's ancestors for three generations.
Cao Cao often has headaches. One day, when Cao Cao was ill, he read this article from his subordinates. Because of the vivid and wonderful writing, Cao Cao became more and more excited, and even his head didn't hurt. Although Cao Cao was angry at Chen Lin's denunciation of himself and his ancestors in the article, he still appreciated Chen Lin's talent and felt sorry for Chen Lin's work for Yuan Shao. Later, Cao Cao defeated Yuan Shao and Chen Lin surrendered to Cao Cao. One day, Cao Cao asked Chen Lin, "When you wrote a campaign against me, you only scolded me. Why did you scold my ancestors for three generations? " Chen Lin said, "I was working under Yuan Shao, and he ordered me to write, so I did. It's like an arrow on the string, you must send it out. There is nothing you can do. " Cao Cao understood Chen Lin's situation at that time, so he didn't punish him and didn't mention it again.
Later, people used "an arrow on the string" to describe the situation as very urgent, and it was time to do something. Sometimes it is also used with "have to send".

Lessons from the past
During the Western Han Dynasty, there was a man named Jia Yi who gave advice to Emperor Wen of Han Dynasty and put forward the principles and policies of governing the country. People say this in their policies: "Hu Hai, the second son of Zhao Gaojiao, the king of Qin, only taught him how to execute prisoners, but did not teach him how to govern the country well. In the end, Hu Hai only knew how to execute prisoners and their families. The day after the death of Qin Shihuang, Hu Hai killed people. At this time, some people advised him that this was a rumor, and some people advised him that this was slander. When he killed someone, he felt that he was mowing the grass. Hu Hai was not so cruel by nature, but was misled by his educators. As the saying goes,' If you want to know an official's attitude, you can judge it by his past performance in office', and some people say,' Learning from the past, learning from the past' ... "After listening to Jia Yi's advice, Wendi really focused on politics, and later the country was well governed by him. During the many years of Emperor Wen's reign, the country was rich and strong, which was known as "the rule of Wenjing" in history.
