What did the first ancients who advocated "healthy tourism" introduce Confucius?

In fact, as early as the Spring and Autumn Period and the Warring States Period more than 2,000 years ago, the ancients had the activity of studying abroad. Historians have researched the historical records of study tour: the word "study tour" is found in the biography of Chun, which says: "study tour has a wide range of knowledge, which means that he can learn a lot because of study tour."

In the history of China, the concept of study tour was first put forward by hundred schools of thought in the pre-Qin period, and the iconic figure of ancient study tour was Confucius in the pre-Qin period. It can be said that Confucius initiated the study tour in China. According to "The Family History of Confucius", Confucius traveled to various vassal states 14 years, covering Wei, Chen, Lu, Song, Zheng, Cai and Chu countries. It is for this reason that Confucius is still preserved in many places. Not only Confucius, but all the "Zi" characters in the pre-Qin period were "wanderers". Mozi, Zhuangzi, Sun Tzu, Mencius, Xunzi and Han Feizi are all famous "tourists".
