In July of the eleventh year of the reign of Duke Heng of Qin (594 BC), Duke Huan of Qin sent troops to attack the State of Jin, and the two armies engaged at Fushi (in present-day Dali County, Shaanxi Province). The Jin general Wei And the Qin general Du Hui fought, and suddenly saw an old man wrapping a straw rope around Du Hui, who stood unsteadily, fell to the ground, and was captured on the spot, and the Jin army won a great victory. It turned out that Wei Qian's father, Wei Wuzi, had a concubine who did not have children, and when Wei Qian was just ill, he ordered Wei To marry the concubine to someone else, and when Wei Qian was critically ill, he ordered Wei Zhen to use the concubine for martyrdom. After Wei Xian's death, Wei Zhen married the concubine to someone else and said, "This is an instruction from my father when he was sober-minded. Later, Wei Fang dreamed of the old man, and the old man said, "I am the father of the little concubine, and I did this to repay you for saving my daughter." This is the allusion to the knotted grass in the idiom "knotted grass ring".

In the twenty-fourth year of the Duke of Qin Heng (581 BC), the Duke of Jin Jing was seriously ill and sent emissaries to the Qin State to ask for a doctor, and the Duke of Qin Huan sent a doctor to the Jin State to treat the Disease of the Duke of Jin.
After the death of Duke Jing of Jin and the succession of Duke Li of Jin, he wanted to ally with the Qin state, so The Duke of Qin Huan of Jin agreed to make an alliance at Linghu (令狐, in present-day western Linyi County, Shanxi). In the winter of 580 BC, the Jin state came to the land of Hexi in advance on the day of the calendar according to the agreement, and happily prepared to establish an alliance with the qin state, where to know that the Duke of Qin Huan did not want to cross the river at all, he camped in Hedong, the Jin state ligong across the river, the most bizarre alliance in the history of the Spring and Autumn Period appeared, the Jin monarch and the Qin diplomat signed an alliance agreement in Hexi, and the Qin monarch signed an alliance agreement with the Jin diplomats in Hedong. There is great uncertainty in this agreement itself, and the two sides uphold an attitude of mutual distrust, so this alliance can be called a formal declaration of war between the two sides. Duke Huan of Qin, who had returned to the Qin state, did not take the alliance as a promise at all, and directly secretly contacted the Di people to attack the Jin state. Realizing the true appearance of Qin Huangong here, Jin Ligong found someone in the Jin State to write a "Book of Absolute Qin" that has been passed down through the ages, counting the crimes of Qin Huangong, sprinkling nearly a thousand words in foreign languages, simply to put it simply, cursing Qin Huangong for "giving face without face", and also sent a sharp-tongued diplomat Wei Xiang to run to the Qin State, formally declare war on the Qin State, and criticize the Qin Huan Duke with unforgivable evil, and from then on, the Jin State and the Qin State completely broke with the Qin State and became an absolute enemy country.
In the autumn of the twenty-sixth year of the reign of Duke Heng of Qin (579 BC), the State of Qin attacked the State of Jin by Bai Di, and Jin defeated Bai Di at Jiaogang. The following year, Duke Li of Jin led an army to the capital of Zhou (near Wangcheng Park in present-day Luoyang, Henan Province) to meet with the armies led by the kings of the Eight Kingdoms of Qi, Song, Wei, Lu, Zheng, Cao, Yi, and Teng to plan an attack on Qin, and King Jian of Zhou also sent his grandchildren Liu Kanggong and Cheng Sugong to lead an army to assist in the battle. In April of the same year, the State of Jin sent the great master Wei Xiang to Qin, and declared war on the Qin State by repeating the three generations of monarchs of Qin Mugong, Qin Kanggong, and Qin Gonggong, undermining the friendship between the two countries, provoking war, and declaring war on the Qin state.
Duke Li of Jin personally commanded the fourth army of the Jin Dynasty, and the generals accompanying the army were the Chinese general Luan Shu and the Chinese army Zuo Xun Geng; the Shangjun general Xie, the Shangjun Zuo Xun; the lower army general Han Jie, the lower army Zuo Xun Zhen; the new army general Zhao Xu, and the new army Zuo Xunzhi. Hao Yi drove the chariot for the Duke of Jin, luan needle for the right side of the car, and there was also the help of the combined forces of the princes. Zhao Rong, the Duke of Qin Huan, saw that the princes' armies were pressing down on the territory and sent troops to the east of the Jing River to confront the combined forces of the princes. In May 578 BC, the two sides fought a fierce battle at Ma Tunnel (ma tunnel in present-day northern Jingyang County, Shaanxi Province), and the Qin army was defeated, and the Qin general Cheng cha and his father were captured. On the side of the princes, Cao Xuangong died in the army. The remnants of the Qin army were defeated, and the combined forces of the Jin division and the princes crossed the Jing River in pursuit of Hou Li (in present-day Liquan County, Shaanxi Province) and retreated.
After this battle, the qin state was seriously injured, and the immature decision of Qin Huangong in political mediation eventually led to the insistence of three generations becoming a bubble, losing fame, losing the war, losing the international image, and losing the development plan of the Qin state. Since then, the Qin state has declined for hundreds of years, diluting it in the shadow of the Jin state.
In the 28th year of the Duke of Qin Huan (577 BC), duke Huan of Qin died and was succeeded by his son Duke Jing of Qin.
