This sentence came from the ancient Chinese novel Romance of the Three Kingdoms, Zhuge Liang's "Book of Commandments". The original text was: "The gentleman's romantic will last forever." This sentence expressed Zhuge Liang's pursuit and admiration for the demeanor of a gentleman. He believed that a person with the demeanor of a gentleman could be passed down in society for thousands of years and be respected and admired by future generations. In the Book of Commandments, Zhuge Liang warned his son Zhuge Zhan: "The way of a gentleman is light on financial thrift, empty use, deep ambition, deep roots, filial piety to relatives and sincere friendship. If you have the strength, you can learn literature." It meant that the demeanor of a gentleman should be indifferent to wealth, save money, maintain noble aspirations and moral character, and be filial to relatives and friends and work hard to practice. This sentence reflected the importance of a gentleman's demeanor in traditional Chinese culture. Zhuge Liang used this to educate his sons, hoping that they would become people with a gentleman's demeanor and be respected and admired in society.
