What do you mean, clean and clear?

Jade is clean and ice is clear, which is an idiom in Chinese. It originated from Huan Tan's new theory and false defects in the Eastern Han Dynasty.

This idiom means as white as jade and as clean as ice; Describe people as pure and virtuous. Its structure is joint and can be used as predicate and adverbial in sentences.

Uncle Boyi, as pure as ice and pure as jade, did not take righteousness as the sole heir of bamboo, did not eat Zhou Su, and starved to death in Shouyang. "(New Theory of False Defects by Huan Tan in the Eastern Han Dynasty) Later generations refined the idiom" Jade is clean and ice is clear ",which is also called" Ice is clean and jade is clean ".

The allusion of "Jade is clean and ice is clear" shows that Boyi and Shu Qi are noble brothers, who fled the lonely bamboo country to defend their righteousness, voluntarily gave up the right to inherit the monarch and refused to eat the salary of the Zhou Dynasty. Their martyrdom was highly praised by Confucianism.
