3. The Oath of the Peach Garden is not in the official history of the Three Kingdoms.

The Romance of the Three Kingdoms, one of China's Four Great Classical Novels (Romance of the Three Kingdoms, Water Margin, Journey to the West, Jin Ping Mei), clearly features the Oath of the Peach Garden. However, the Romance of the Three Kingdoms is a novel based on the historical text, Records of the Three Kingdoms. The Oath of the Peach Garden does not appear in the official historical records of the Three Kingdoms. While it's true that Liu Bei, Guan Yu, and Zhang Fei were close like sworn brothers, this was a plot device added for narrative interest in the novel and does not appear in the historical records. Since the content is short today, let's also look at some representative Chinese idioms that appear in the Three Kingdoms. Sāngāo chǔliè (Liu Bei visits Zhuge Liang three times; implies patience and effort in welcoming talented individuals) Yìn chānmǎ sù (To behead Ma Su with tears; means to uphold order by punishing a subordinate according to the law) Shuǐyúzhījiāo (Like water and fish; refers to an inseparable and intimate relationship) Nánxíngnánzhě (Difficult to call him older brother, difficult to call him younger brother; describes a relationship where it's hard to distinguish who is superior) Fúlóngfèngzhuī (A hidden dragon and a phoenix chick; refers to outstanding talents who have not yet revealed themselves) Gǔyǒuzhīcè (A stratagem that involves sacrificing oneself)
