Rebuild the spiritual value for the society, establish the meaning of life for the people, inherit the lost academic system for the former saints, and open up the foundation of peace for all generations.

This sentence was said by Zhang Hengqu, a great scholar in the Northern Song Dynasty. Zhang Zai (1020- 1077), a native of Hengqu Town, Yanxian County, Fengxiang County (now Meixian County, Shaanxi Province), was a thinker, educator and one of the founders of Neo-Confucianism in the Northern Song Dynasty. Known as Mr. Hengqu in the world, Zhang Zi is honored as a saint, and he is thirty-eight in the west of Confucius Temple. His famous saying, "Make a heart for heaven and earth, be a man, link the past with the future, and create peace for all generations", was called "four sentences in a horizontal canal" by contemporary philosopher Feng Youlan. Because of its simplicity and grandeur, it has been praised by people throughout the ages.

A scholar's mind is based on heaven and earth, that is to say, he is broad-minded and knows how heaven and earth work, so he does not doubt this practice. To live for the people is to serve the people, and it is our duty to rehabilitate the wrongs. In order to make the past serve the present and inherit the theory of ancient saints, we should study hard and never get tired of it. To create eternal peace, we should also wave flags and shout for eternal peace to prevent instability in troubled times.
