For thousands of years, Confucius' wisdom has nurtured generations of wise men. Even today, it has incomparable practical value. In today's society, people excessively pursue money, material and sensory enjoyment, resulting in physical and mental disorders, spiritual loneliness, and split personality. Under such circumstances, knowledgeable people think of the wisdom of Confucius. Dr. Hannes Alven of Sweden, Nobel Prize winner in physics, said: "If humans want to survive in the 21st century, we must look back 2,500 years to absorb the wisdom of Confucius."
