Sweating for Liu Bei's restoration to the Han Dynasty-this persistent spirit embodies the lofty integrity of the Chinese nation and the "benevolent spirit" at the core of Confucian culture. Some scholars have explained it very well: the word "benevolence" is from person to person, and the upper horizontal plane of the word "benevolence" is the sky and the lower horizontal plane is the ground, so the person who stands tall is called "benevolence". Zhao Yun is an indomitable iron man edified by Confucian culture, and an example for us in China to learn and admire.
