Zhu Xi helped shape Neo-Confucianism. This is a way of thinking about life and morals. He believed that everything in the world has two parts. One part is called li, which is a rule or principle. The other part is called qi, which is the physical matter. He thought that every person has a perfect li inside them. This means people are born with goodness. However, our qi can sometimes hide that goodness. We must study and practice to clear our qi.
He taught that knowledge and action go together. He said they are like legs and eyes. You need both to walk and see well. He also used a type of quiet thinking called meditation. This helped him stay focused and calm. His ideas became very important in China for a long time. They were even used in school tests until 1905. His work spread to Japan, Korea, and Vietnam too.

Zhu Xi was born in Fujian. His family came from Wuyuan County. He was a very bright child. At age five, he asked what was beyond Heaven. By age eight, he understood important books about family. He passed a big government test when he was 19. He served as a registrar in Tong'an from 1153 to 1156. Later, he became the leader of the Nankang Military District. He also helped bring back the White Deer Grotto Academy.
Zhu Xi spent much of his life teaching. He believed that learning was the only way to become a wise person. He wrote and edited almost one hundred books. He also wrote many notes to explain the Four Books. These books include the Great Learning and the Analects of Confucius. His notes became the standard way to teach these classics. He taught his students to investigate things to find moral truths. He said knowledge and action must always go together. He compared them to eyes and legs. 
Life was not always easy for Zhu Xi. He had political rivals who did not like his ideas. One man named Han Tuozhou was a major rival. Because of this, Zhu Xi was sometimes removed from his jobs. Even so, many people loved his teachings. After he died, the Emperor honored him with special titles. One title was the Duke of Hui. In 1241, a memorial was placed in a special temple for him. Today, he is known as one of the great Confucian philosophers.
Zhu Xi was a central figure in Chinese intellectual history. 
Zhu Xi's philosophy relied on the relationship between two universal aspects of reality. These are known as li and qi. Li is the rational principle or law that governs all things. Qi is the physical or material force that makes up the world.
These two forces, li and qi, operate in a state of mutual dependence. When their activity is expansive or rapid, it is called the yang energy mode. When their activity is slow or contractive, it is called the yin energy mode. The constant interaction between yang and yin leads to the evolution of the five elements. These elements include fire, water, wood, metal, and earth. Zhu Xi argued that li existed even before the creation of Heaven and Earth. This metaphysical system explains how the physical world and moral laws are connected.
Zhu Xi applied these ideas to human nature and morality. He believed that every individual possesses a perfect li. This means that human nature is inherently good at its core. However, he taught that our physical qi can obscure this perfect moral nature. The goal of moral cultivation is to clear our qi so we can act rightly. He used the term xin to describe both the heart and the mind. To Zhu Xi, clarity of mind and purity of heart were essential for a virtuous life. He even compared the mind to a mirror that reflects the world clearly.
To achieve this clarity, Zhu Xi emphasized specific methods of learning and practice. He advocated for the "investigation of things," or ge wu. This involved paying close attention to both books and daily affairs to find moral principles. He also believed that knowledge and action were indivisible. He famously compared them to a person's eyes and legs. One cannot walk effectively without legs, and one cannot see without eyes. Knowledge provides the necessary forethought, while action produces the actual effect. 
Zhu Xi's career was marked by both academic success and political struggle. He passed the Imperial Examination at age 19 and served as a Subprefectural Registrar in Tong'an. He later became the Prefect of Nankang Military District and revived the White Deer Grotto Academy.
His educational impact was massive and long-lasting. He chose to focus on the Four Books: the Great Learning, the Doctrine of the Mean, the Analects, and the Mencius. He wrote extensive commentaries on these texts. These commentaries became the standard curriculum for the imperial civil service examinations. This system remained in place from 1313 until its abolition in 1905. His teachings moved the study of classics from simple philology to deep philosophy. His influence extended far beyond China, shaping the social hierarchies and values of Japan, Korea, and Vietnam for centuries.
