The Chinese expression "Three Zhang Four Li" () is used to mean "anyone" or "everyone", but the most common surnames are currently Wang in mainland China and Chen in Taiwan. A commonly cited factoid from the 1990 edition of the "Guinness Book of World Records" estimated that Zhang was the most common surname in the world, but no comprehensive information from China was available at the time and more recent editions have not repeated the claim. However, Zhang Wei (张伟) is the most common "full" name in mainland China.
