In literary creation and aesthetics, it refers mainly to a pure state of being filled with subtle feelings and noble ideals, transcending all worldly pursuits and sophistication, and rejecting an overly rational mentality lacking aesthetic judgment.

Brothers and Sisters of the Same Parents; Compatriots

This term originally referred to siblings in the same family. Based on the belief that all living creatures are created by heaven and earth, Zhang Zai (1020–1077) of the Northern Song Dynasty advanced the view that all people were brothers and sisters and all living things companions. The meaning of the term was thus extended from blood ties to include people of the same nation or state, especially those with a common language and culture. Sometimes the term goes beyond the nation to refer to all of humanity. Tracing common ancestry, language, and culture, rouses and strengthens people’s sense of identity and recognition of their nation and state. Equality and the universal love it embodies are a source of inspiration for humanity.

以“道”拯救、帮助天下的人。“道”指道理、道义，也可以是某种学说、思想等；“济”即救助，使人免于困苦；“天下”指世间所有的人。“道济天下”包含两层意思：其一，“道”的价值有无、大小就是看它于天下人是否有益。其二，君子特别是知识分子应该将自己所主张或掌握的“道”用于天下、用于经世济民。和“经世致用”一样，“道济天下”实质代表中国传统知识分子治学立世的终极目标与人格理想，体现了中国传统知识分子追求真理、坚持真理、关注社会民生以及“以天下为己任”的人文情怀和道德境界。

The term means to save and help all people through upholding truth and justice. Dao (道) here refers to truth and justice, and also to particular thought or doctrine. Ji (济) means relieving or helping people out of difficulties or sufferings. Tianxia (天下) refers to everything under heaven, and particularly all people. Therefore, this phrase contains two meanings. First, the value of any particular Dao depends on whether it serves the interests of the people. Second, people of virtue, and intellectuals in particular, should apply the Dao they have learned to serve the people and use the ancient classics they have studied to meet present needs. Much like the idea of "studying ancient classics to meet present needs," this notion of "supporting all people by upholding truth and justice," represents the ultimate goal and ideal character of the traditional Chinese intellectuals in their pursuit of knowledge. It also embodies the compassion and moral standards of the traditional Chinese intellectuals as they pursue and uphold truth, care about the livelihood of the people, and take upon themselves the responsibility for the world.

This term refers to a person acting courageously to do what is righteous. This fine tradition hailed by the Chinese nation since ancient times establishes that a man should be committed to upholding justice and shouldering social responsibility. Today, such acts are protected by law. Some administrative regulations provide that "acting bravely for a just cause" refers to an action of a citizen who fights to stop any on-site criminal acts or acts in an emergency to protect state property, public interests, people, or their property from danger disregarding his safety. Whether in ancient days or today, acting bravely for justice is always a commendable ethical deed and also an important indicator of social progress.
