At the end of the Southern Dynasties, Emperor Wen of the Sui Dynasty, Yang Jian, conquered the neighboring states of Southern Chen and Northern Qi, establishing the Sui Dynasty. At that time, several small states coexisted in southern China, one of which was the Chen Kingdom, whose capital was Jiankang (present-day Nanjing). The Sui Dynasty had long coveted these southern states and was always prepared to unify the entire country.

This idiom appears in the "Records of the Grand Historian: Biographies of Wei Qi and Marquis Wu'an": "After Marquis Wu'an had finished court, he exited to the Zhi Che Gate, summoned Grandee of the Imperial Censors Han An'guo to ride in his carriage, and angrily said, 'Having worked with Changru to deal with this old bald man, why are you hesitating between two courses of action?'"

Lu Ban (also known as Gongshu Ban or Lu Ban), was said to be a native of the State of Lu during the Warring States period. He was a master craftsman renowned for his skill in making intricate tools and was known as the "ingenious man." Folk tradition has long revered him as the founding ancestor of carpenters. Who would dare show off their axe skills in front of Lu Ban? Thus, attempting to display one's abilities in front of a true master—a presumptuous and ridiculous act—is called "wielding an axe before Lu Ban's door," shortened to "Banmen Nongfu" (showing off before an expert). It carries a similar meaning to the common saying, "waving a broadsword before Guan Gong" (Guan Yu, the martial deity).

During the Warring States period, there was a noble scholar in the State of Qi named Yan Chu. King Xuan of Qi, having heard of his reputation, summoned him to the palace. Yan Chu walked casually into the palace and stopped at the steps before the hall, seeing that the king was waiting for him to come forward and pay his respects. He halted, refusing to advance further. The king, finding this strange, called out, "Yan Chu, come here!" But to his surprise, Yan Chu did not move an inch and instead called back, "Your Majesty, please come here!" King Xuan was displeased. His ministers, seeing Yan Chu's apparent disrespect and bold words, exclaimed, "The king is the sovereign; you are a subject.

In the towns and villages of Zhejiang province, there is a famous dish known to every household, associated with the great Song Dynasty literary master Su Shi. Called "Dongpo Pork," it has been passed down for nearly a thousand years, and its story is quite fascinating.

Wu Song had just downed eighteen bowls of wine at an inn not far from Jingyang Ridge. He walked unsteadily, dragging his cudgel behind him, about to head toward the ridge. The innkeeper ran out after him, shouting: "You can't go! You can't go! There's a tiger on the ridge recently—it's already killed twenty or thirty people!" Wu Song merely smiled and said, "Don't try to scare me. Even if there really is a tiger, I'm not afraid!"

A famous prophecy passed down from the Ming Dynasty, "The Song of the Baked Bun," was authored by Liu Ji, the Imperial Preceptor during the reign of the Hongwu Emperor of the Ming Dynasty, also known as Liu Bowen. It is said that Liu Ji had profound knowledge of mathematics and numerology, and folk legends claim he was a celestial being descended to earth to assist the founding emperor in establishing his great enterprise. In folk tales and literary works, he is often depicted as possessing extraordinary foresight, capable of predicting the future without divination, understanding the past and present, and even commanding wind and rain with immense supernatural powers—described as knowing "five hundred years before and five hundred years after"—a figure as divine as a celestial being.

In the second year of Jingkang, during the reign of Emperor Qinzong of the Song Dynasty (1127 AD), the Jurchen (Jin) army marched southward, sweeping through undefended territories and swiftly capturing Bianliang (present-day Kaifeng, Henan), taking Emperors Huizong and Qinzong captive. This event is historically known as the "Humiliation of Jingkang." Following this catastrophe, Zhao Gou, younger brother of Emperor Qinzong (Zhao Huan), ascended the throne in Ying天府 (present-day Shangqiu, Henan) with the help of his ministers, establishing the Southern Song Dynasty. Later, the capital was moved to Lin'an (present-day Hangzhou, Zhejiang). The regime merely clung to survival, accepting all unreasonable demands from the Jurchen without resistance. By the time of Emperor Lizong, the appointment of the treacherous minister Jia Sidao as chancellor further plunged the court into chaos.

During the Warring States period, Bian Que was a renowned physician from the state of Qi, originally named Qin Yueren. Because he saved many people who were on the brink of death, people at the time began calling him "Bian Que"—the legendary divine physician from the era of the Yellow Emperor—instead of using his real name. Legend has it that Bian Que once received immortal medicine and secret prescriptions, enabling him to diagnose patients through walls and clearly see the internal organs and exact locations of diseases within their bodies.

After Emperor Taizong of Song ascended the throne, fully aware of the hardships of founding a dynasty, he lived a very frugal life. He even banned the use of gold and silver as decorations in the imperial palace. He deeply empathized with the people's sufferings and always considered their well-being and the stability of the state.
