During the Warring States period, in order to consolidate their political power, the princely states carried out a campaign to change the law through talent. The success of Wei Guoli's slow change of law aroused great interest from Qin Xiaogong. Qin Xiaogong believed that the Qin state could only become stronger through the law change movement, so he recruited talents in the Qin state, hoping to find a person who changed the law.

After Shang Martin came to the Qin kingdom, he was supported by Qin Xiaogong. Under the impetus of Qin Xiaogong, Shang Martin began a large-scale movement to change the law.
As a result of the implementation of the ruling class, the Martingale Transformation Law was successfully implemented. Duke Xiao of Qin ordered Shang Martin to implement the change in the Qin state. Therefore, for Shangmartin, the resistance to reform is greatly reduced. With the support and promotion of Qin Xiaogong, the Shang Martingale Transformation Law was successfully implemented in the Qin State.
The quotient martingale transformation method conforms to the trend of the times, which is the second reason for the success of the quotient martingale transformation method. In the context of the Warring States period, the strength of the state not only lies in the vast land area, but only if the country is rich and strong, and the military combat effectiveness is strong enough, it will not be annexed by other princely states. All the princely states wanted to put their own countries on the path to strength through reform. Shangmartin reformed in Qin, conformed to the development trend of the times, and won the support of the Qin people.
Shang Martin himself unremittingly promoted the process of changing the law, so that the change of law was deeply rooted in the hearts of the people. As reformers, we must have perseverance, perseverance and confidence. The martingale harmed the interests of the aristocratic class in the process of changing the law. They also resisted and discouraged the martingale, but the aristocratic approach did not cause the martingale to terminate the change. On the contrary, the martingale goes deep into the process of changing the law, so that the martingale transformation method is deeply rooted in the hearts of the people.
The two changes in the martingale of the Qin state made the Qin state embark on the road to prosperity and strength.
