banknotes from the Fourth Series of the Renminbi (RMB),

banknotes from the Fourth Series of the Renminbi (RMB), which was issued by the People’s Bank of China starting in 1987. These notes are largely out of general circulation today, having been replaced by the Fifth Series (the ones featuring Mao Zedong on the front). ​Here is a breakdown of what you have: ​1. The Top Note: 1 Yuan (Yi Yuan) ​Front: Features two women in traditional ethnic clothing (Yao and Dong ethnic groups). ​Back: Features the Great Wall of China. ​Series Year: Likely 1980, 1990, or 1996 (the specific year is printed in small text on the back). ​Value: 1 Yuan. ​2. The Four Bottom Notes: 1 Jiao (Yi Jiao) ​Front: Features two men in traditional ethnic clothing (Gaoshan and Manchu ethnic groups). ​Back: Features the national emblem of the People's Republic of China. ​Denomination: In the Chinese currency system, 10\text{ Jiao} = 1\text{ Yuan}. These are essentially "10-cent" notes. ​Series Year: These are the 1980 edition. While the 1980 series has been officially retired, the 1 Jiao and 5 Jiao notes are unique because they were never formally "recalled" in the same way larger bills were, though they are rarely seen in modern city commerce.
