建筑工人离不开尺。古语说:“度然后知长短”。长短需要用一种公认的工具来测量。在很早以前,人们用中指和拇指伸开后的长度,作为量物的依据,俗话叫“一虎口”。《尚书·舜典》中记载,舜接尧位后,到四方巡狩,把各氏族的度量衡都协同起来。公元前221年,秦始皇赢政颁发统一度量衡诏令,还规定了校定制度,由官府制发度量衡标准器。秦代的一尺等于现在的0.2309米,折合0.6928市尺。 Construction workers cannot leave the ruler. The old saying goes: “degree then knows length”. The length needs to be measured with a recognized tool. Long ago, people used the length of the middle finger and the thumb to extend it as a basis for the quantity. The saying is called “a tiger’s mouth.” According to the “Shang Shu Dian Dian”, after taking the throne, he went to the Quartet for patrolling and coordinated the clan’s weights and measures. In 221 BC, Qin Shihuang won the government and issued a unified measurement and measurement order. It also stipulated the schooling system. The foot of the Qin Dynasty is equal to the current 0.2309 meters, equivalent to 0.6928 city feet.
