According to the statistics of UNESCO, the Bible is the most published book in the world, and the Tao Te Ching is the second most published book, which has been translated into many languages and widely circulated! It is a great spiritual wealth of China and even the world! In the 20th century, although mankind has made rapid progress in science and technology and material wealth, it has also caused three major crises: environmental damage, value confusion and spiritual pollution. Faced with these social crises, westerners began to seek philosophical wisdom from Oriental Taoism to solve practical problems.

American scholar Michael hart pointed out when commenting on Laozi's Tao Te Ching: "Although this book is less than 6,000 words, it contains a lot of spiritual food." Kristofer Schipper, a professor at Leiden University in the Netherlands, affirmed that Taoism "is a rare source of power and vitality of western culture." Gao Chuang, a professor at Harvard University in the United States, thinks that the Tao Te Ching is "a valuable textbook about human behavior". Julius Gail, a German, pointed out: "Laozi, he is the driving force for the future. He is more modern than any modern person. He is more energetic than any life. " Will Duran, an American scientist, thinks Tao Te Ching is "the most fascinating book". Nietzsche, a German philosopher, thinks that Laozi's Tao Te Ching is "like an inexhaustible Jing Quan full of treasures." American scholar Pu Keming predicted that "The Tao Te Ching will be a family heirloom." The reason why it is so valued and respected by the world is that it is the oldest and most systematic first Dacheng Wisdom.

Politically, many countries have pointed out that to build a "harmonious society" and a "harmonious world", we must be good at finding political wisdom from Laozi's Tao Te Ching. Former German Chancellor Gerhard Schroeder appealed loudly that every German family should buy a copy of China's Tao Te Ching to help solve people's ideological confusion. Former US President Ronald Reagan quoted the famous saying in the Tao Te Ching that "governing a big country is like cooking small fresh food" in order to seek his idea and strategy of governing the country. Former Russian President Dmitry Medvedev suggested that the whole world "follow the teachings of Laozi, a great philosopher and thinker in ancient China, to deal with the world financial crisis". UN Secretary-General Ban Ki-moon spoke highly of Laozi's Tao Te Ching, quoting Laozi's "Heaven is beneficial but not harmful; The way to be a saint is to fight for it and try to apply this immortal philosophical wisdom to the work of the United Nations.

Economically, in order to solve the problems in the modern market economy, we also need to look for the philosophical wisdom of developing the economy from the Tao Te Ching. British philosopher Clark believes that "the principle of free market in modern economy comes from Lao Tzu's inaction." In the world, an economic and cultural group "Shang Dao" has quietly risen. The so-called "Taoist businessmen" are businessmen engaged in enterprise management with Taoist dialectical thinking and philosophical wisdom. Mr. Annan Borg, President of Alstom, said: "To do business in China, you must know Lao Zi." James, a former executive of Fortune 500 companies, regards Tao Te Ching as a business theory in the new century. Austrian economist Hayek believes that Taoism's "I do nothing and the people make it;" The view that I am quiet and the people are self-righteous is a classic expression of his theory of spontaneous order. Bill Gates, the founder of Microsoft Corporation in the United States, is engaged in social charity according to Laozi's idea that "Heaven can make up for more losses". Jack Welch, former president of American GE Company, advocated "inaction" and "simple management" according to Lao Zi's thought of "beggar-thy-neighbor".

In terms of science and technology, the development of modern science and technology can also be inspired by Laozi's Tao Te Ching. Inspired by Laozi's thought that everything in the world is born in existence and everything is born in nothingness, British scientist Hawking put forward the theory that the universe is born in nothingness. The "simplicity principle" put forward by john wheeler, an American physicist, coincides with Lao Zi's so-called simplicity of Tao. Li Zhengdao, an American Chinese, found that the "uncertainty principle" in quantum mechanics also coincides with Laozi's thought that Tao can be Tao, but not surprising. Masanobu Fukuoka, a Japanese agronomist, put forward "natural farming" and claimed that he was "inspired by Lao Zi's great proposition of" Taoism is natural ".
