《资治通鉴·齐纪·齐纪三》
从汉代铸制五铢钱到宋文帝时期，历时五百多年，各朝各代的制度有立有废，但却自始至终使用五铢钱的原因，就是因为人们明白五铢钱轻重恰当、交易方便。
自汉铸五铢至宋文帝，历五百馀年，制度世有废兴，而不变五铢者明其轻重可法、得货之宜故也。
From the casting of the five-zhu coin in the Han Dynasty to the period of Emperor Wen of the Song Dynasty, spanning over five hundred years, each dynasty had varying systems that were established and abolished, but the reason why the five-zhu coin was used from beginning to end was because people understood that its weight was appropriate and it was convenient for trading.
