Build a letter tree
Not an idiom, but a story. During the Warring States Period, after Qin Xiaogong, king of Qin, ascended the throne, he was determined to reform and recruit talents. Shang Yang entered Qin State from Wei State, and put forward a set of reform and innovation development strategies, such as abandoning ore fields, attaching importance to agriculture and mulberry, rewarding meritorious military service, implementing unified quantity and establishing county system, which won Qin Xiaogong's trust and made him a regular in Zuo Shu. In 356 BC and 350 BC, the method of "abandoning ore fields, building buildings, implementing county system, appreciating farming and fighting, and practicing sitting together" was implemented twice.
After Shang Yang's political reform, Qin's economy developed, and the fighting capacity of the army continued to strengthen, and it developed into the most prosperous feudal country at the end of the Warring States Period.
