Vehicle on the same trackFirst Emperor of QinBefore the unification of the Central Plains, there was no unified system in all countries. The size of carriages was different in different regions, so the lanes were wide and narrow.
The country is unified, and vehicles have to walk on different lanes, which is inconvenient.Since then, the distance between the two wheels on the vehicle has been changed to six feet, so that the distance between the wheels is the same.In this way, it is convenient for vehicles to travel around the country.This is called "car on the same track".
Train on the same track: nationwideRutThe width is the same as the width.Unify words and ruts.It means national unity.In ancient times, all roads were earth roads. After repeated rolling by wheels, two hard ground lanes with the same width as the wheels would be formed.When the carriage is transported for a long distance, keep the wheels on the hard road all the time, and walk steadily, which can significantly reduce theanimal powerConsumption and axle wear are just like modern vehicles walking on asphalt roads.The law of the Qin Dynasty on the same track for cars can make roads all over the country into hard ground lanes with the same width within a few years, which can not only reduce goods and passengersTransportation processIt is also beneficial for the Imperial Army to be able to carry materials to any county in the country quickly.Therefore, the same track isthe Qin stateImportant strategic measures of unity.
The earliest record of "vehicle on the same track" is《The Doctrine of the Mean》, the original text is as follows:
Confucius said: Foolish but good for self use, cheap but good for self-study.Born in today's world, it is against the ancient way.Such a disaster and its body are also.
If it is not the Son of Heaven, no ceremony, no system, no text.Get off today, the train is on the same track,A book is a prose, line homotopy.Although he has his own position, he has no virtue, and dare not make rites and music.Although he has his own virtue, he has no position, and he dare not make rites and music.
Confucius said, "When I say Xia Li, Qi is not enough to levy.".My learningYin LiThere is Song Cunyan.My learningZhou Rites, used today.I follow Zhou.[3]
From the content of the original textZhou DynastyWhen a unified country was formedGauge、moralUnification has become a national policy.After the split and scuffle of the Spring and Autumn Period and the Warring States Period, when countries developed independently in their respective regions, they more or less deviated from the various systems established by the Zhou Dynasty, that is, the so-called "ritual collapse and music destruction".ConfuciusAnd its foundingconfucianThe core idea is thatsocial problemThe emergence of "Li" originates from people's deviation from the system of the Zhou Dynasty - Zhou Li. Only everyone works hard to revive Zhou Li, and the monarch and his subjects, father and son, follow each otherDuke ZhouAll problems can be solved by the rules of the week.
Qin DynastyAfter the establishment, "one method is equal to the stone. The car is on the same track. The book is on the same word." Various measures have objectively promoted the substantive integration and unification of the original seven countriesChinese civilization The achievements of the formation and development of.
