BEIJING, April 4 (Xinhua) -- The Chinese idiom "wide hearts embrace all," or "You Rong Nai Da," is often used to describe people who are big-hearted or broad-minded.

It comes from the ancient "Shangshu," one of China's earliest compilations of historical documents.

The Duke of Zhou from the Western Zhou Dynasty (1046-771 B.C.) was renowned for acting as a capable and loyal regent for his young nephew King Cheng of Zhou.

After the duke died, the King Cheng of Zhou decided to nominate the duke's second son Jichen to rule Chengzhou, the capital city.

"Be tolerant and you will have a strong moral virtue," the King Cheng of Zhou told Jichen before the appointment.

The king's words were quoted by many notabilities in later generations and evolved into the idiom. With time, the concept has developed into a societal norm in China, as people are encouraged to be tolerant and seek common ground while reserving differences.
