The "saints" under the inner route are spiritual saints (saints under the psychological route), while the "saints" under the outer route are saints at work (saints of heavenly creations). Their "achievements" generally correspond to morality and science. This is the true state of "sanctification" under the Confucian cultural tradition, which is also the fundamental basis for why Confucianism can be called Confucianism (non-Christian Catholicism) as "heavenly religion". Its remarkable feature is that it does not have and does not need the concept of "original sin" like Christianity. Unlike Christianity, people like Jesus pretend to be messengers from heaven and preach to people in the name of God. It holds that people can know, comprehend and discover the will and secret of "Heaven" from the nature, principles, order and everything in the world in their own hearts, and obey and convert to "Heaven" in spirit (China people call death "Death in Heaven" and the so-called "Death in Heaven"). Sages and Confucius are properly regarded as "wise and knowledgeable" (the golden mean), so they just teach their spiritual realm, perception, understanding and knowledge to others as "teachers" who grasp the Tao, while others are just "friends with fate" under "all kinds of troubles" (freedom of thought). Under the concept that "God has a heaven that will always be called" (Zhang Zai's True Dream), anyone can explore ("explore"), know, understand and discover the laws and will of heaven, instead of pretending to be God to "preach" or communicating with God only through the church. This kind of religious characteristic extends to religion in the west. This is why ancient China was ahead of the world in many aspects, and Chinese civilization is considered as the most fundamental reason for the precocity of civilization. It should be noted that compared with the logicism (logical rationality) and epistemological tradition of western ancient Greece and Rome, China's cultural tradition is relatively weak in this respect and needs to be absorbed and used for reference. In fact, this is also an important reason why despite the above-mentioned important cultural background and potential possibilities, China has never succeeded in developing democracy, science and large industry in the modern sense, thus learning from the West in modern times, especially under the slogans of "May 4th Movement", "Mr. Sai" and "saving the country through industry". Under the spiritual structure of harmony between man and nature in China's cultural tradition, when people can make use of and rely on their own conscious spirituality, fully develop and learn from instrumental rationality and their own abilities, and pursue the spiritual realm of "reaching heaven and know life", under the profound religious spirit, morality ("benevolence, righteousness, courtesy, wisdom and trust"), science ("naturally creating things" and "teaching things"), art (The Bell of Love) If Confucianism can absorb Indian Buddhism and China Taoism, then the outside of Confucianism can absorb western learning, making China's Confucian cultural tradition the most inclusive and compatible in the world, while maintaining its own basic cultural characteristics and consistent cultural traditions. This is due to the great possibility of the spiritual line of internal and external cultivation and the spiritual structure of harmony between man and nature in the deep structure of Confucian cultural tradition. This should be the continuous ideological creation of modern neo-Confucianism. Today, it is time to systematically expound the modern neo-Confucian theory which is consistent, internally coordinated and eclectic, inherit the Confucian orthodoxy and open up the modernity of Confucianism. It is the fundamental reason that China tradition has tenacious vitality and the ability of cultural regeneration that "being big first, but being small can't be taken away".
