Ban Jing Dao So, also known as "Ban Jing Dao Old", which means that the thorn strip is spread out on the ground, sitting on it to narrate the old feelings to each other, describing the reunion of friends after a long absence, and recounting the old feelings together. The idiom comes from Zuo Qiu Ming's "Zuo Chuan: The Twenty-sixth Year of Xianggong" in the Spring and Autumn Period, "Wu Ju Ben Zheng, will go to Jin." Shengzi will be like Jin, meet in the suburbs of Zheng, Ban Jing Xiang and food, and return to the past. ”
During the Spring and Autumn Period, the Chu State Doctor Wu participated in Cai Guotai's friendship with the master's son, and the two had a very close relationship and often walked back and forth. Over time, the relationship between the two families became closer and closer, and later Wu Shen's son Wu Ju and Zichao's son Gongsun Guisheng (Trumpet Shengzi) also became good friends.
Since the king of Chu Zhuang, the state of Chu has maintained the tradition of having princes serve as commanders, but these princes have held the power of the court and become more and more powerful, which has seriously threatened the royal power. In order to take back power, King Chu Kang promoted the reform of internal affairs, killed Ling Yin Zinan and Che Split Guanqi, and began to select talents from the clan to serve as Ling Yin.
In the twenty-sixth year of Lu Xianggong (547 BC), in view of the internal turmoil of Chu State, Wu Ju's father-in-law, Prince Mou, fled from Chu State, and at that time the people of Chu State said that Wu Ju let him go, Wu Ju was worried about being implicated, so he also fled from Chu State, planning to go north and flee to Jin State through Zheng State.
Early that morning, Wu Ju was walking on the outskirts of Zheng Guodu, when he suddenly heard someone calling him behind him, and when he looked back, he found that it was his friend Gongsun Guisheng. The two who haven't seen each other for many years are very happy to meet in a foreign land.
So, they broke off the wattles on the side of the road and spread them on the ground, then took out dry food and sat opposite each other, eating and chatting. After Gongsun Guisheng heard what happened to Wu Ju, he comforted him and said, "If you go to the Jin State for the time being, I will definitely find a way for you to return to the Chu State." ”
Gongsun Guisheng was ordered to send an envoy to the Jin Kingdom, so he went to the Jin Kingdom with Wu Ju. Soon after Gongsun Guisheng completed the mission and returned to Cai, he was ordered to send an envoy to Chu and was received by Yin Qujian (Zimu), the commander of Chu.
Qu Jian knew that Gongsun Guisheng had returned from the Jin Kingdom, so he asked him about the situation in the Jin Kingdom, and asked, "Compared with the doctors of the Jin Kingdom and the Chu Kingdom, who is more virtuous?"
Gongsun Guisheng replied, "The secretary of the Jin State is not as good as the Chu State, but their doctors are very virtuous and have the talent to be the secretary." Moreover, just like wolfberry, catalpa wood and leather, these talents were all exiled from the Chu State to the Jin State. Therefore, people say that although Chu is talented, Jin is practical. ”
When Qu Jian heard this, he asked again, "Isn't there a fellow clan and in-laws in the Jin Kingdom who are doctors?"
Gongsun Guisheng replied, "Although there are some, they do have a lot of talents who use the Chu State. I have heard, 'Those who are good for the country will not be rewarded and punished.' Excessive rewards will inevitably be rewarded to the bad people, and excessive punishment will inevitably punish the good people. Even if we exceed the limit, we would rather reward too much than abuse the punishment, which is the fear of losing talent.
In the Book of Songs, Daya Zhanyin, it is said that "without virtuous people, the country will be in danger." The Book of Summer says, "It is better to spare the criminal than to kill the innocent," which is the fear of losing talent. Nowadays, the state of Chu often abuses its punishment, and the doctors have fled to other countries one after another, and have become important advisers of those countries, isn't this a danger to the state of Chu? This is the reason why the talents of the state of Chu were used by the state of Jin. ”
Gongsun Guisheng continued, "In the rebellion of Chu Ziyi, the Duke of Xi fled to the Jin State, and the Jin State reused it. During the Battle of Circling the Corner, the Jin army originally planned to escape, but the Duke of Xi persuaded the Jin army to launch a sneak attack at night, thus defeating the Chu army, and then attacked Cai and Shen, captured the king of Shen, and defeated the Chu army in Shen and Xi at the Sang Tunnel, and captured the Chu doctor Shen Li. After that, Zheng Guo did not dare to get close to the Chu State, and the Chu State lost the Central Plains vassal state, which was all the idea of the Duke of Xi. ”
Later, Gongsun Guisheng cited the cases of Yongzi fleeing from the Jin State and helping the Jin State defeat the Chu State at Pengcheng, causing the Chu State to lose its eastern vassals; Ziling's escape from the Jin State made Wu and the Jin State befriended the State and helped the Wu people improve their national strength to contain the Chu State; and the Ben Emperor fled to the Jin State and helped the Jin State defeat the Chu State in the Battle of Yanling.
These are all facts that have happened in history, and Qu Jian naturally can't refute them, so he can only admit that what Gongsun Guisheng said is correct. Gongsun Guisheng continued, "Wu Ju married the daughter of Prince Mu of Shen, and Zi Mu fled for his crimes, and Wu Ju was also implicated because he was afraid of fleeing to Zheng Guo and hoped to be pardoned. Now that Wu Ju is in the Jin State, and the Jin State is ready to use him as a high-ranking official, if he also helps the Jin State to deal with the Chu State, won't it become a disaster?"
After hearing this, Qu Jian was indeed worried that Wu Ju would be reused by the Jin State, so he hurriedly entered the palace to persuade King Chu Kang to pardon Wu Ju, and increased Wu Ju's Juelu, and sent people to welcome him back to China. So, Wu Ju returned to the state of Chu, Wu Ju's son was Wu Hao, and his grandson was Wu Zixu.
