Notes & fun facts
Financial uppercase digits date back to the Tang dynasty: characters such as 壹贰叁肆伍陆柒捌玖 were created to make accounts hard to alter. Ancient merchant houses wrote amounts with these secure digits on bills and contracts — and today invoices, contracts and bank documents still follow the same rule.
Origin & history
There were famous disputes over a misread 三十而立, and accounting errors caused by sloppy handwriting of 一 and 二. In 2004 the People’s Bank of China made uppercase amounts mandatory on bank instruments, turning Chinese financial uppercase into the standard for financial documents.
