Xu is a Chinese unit of currency that is used for monetary transactions within the People's Republic of China. It is a subdivision of the yuan, which is the main official currency of China. The xu is the smallest denomination of the yuan and is equivalent to one-tenth of a Chinese yuan.
Historically, xu coins were minted with a square hole in the center, which allowed the coins to be easily strung together. These coins were commonly used in daily transactions in ancient China. However, as the Chinese currency system evolved, xu coins ceased to be produced and were replaced by other forms of currency such as paper money and electronic transactions.
In modern times, the xu is mostly used in a non-physical form, through online transactions and electronic payments. It is often referred to as "fen" in colloquial language, which has a similar value and usage. One yuan is equivalent to ten fens or xus.
The xu holds a small monetary value, making it more suitable for transactions involving fractions of a yuan. It is commonly used for pricing small, inexpensive items or for making precise calculations in business transactions. However, due to the low value, the xu is becoming less significant in everyday transactions, as higher denomination notes and electronic payments are becoming more prevalent.
