4. Cultural Background and Notes

• Source: This idiom originates from the 'Encouraging Learning' (劝学 - Quàn Xué) chapter of the Xunzi (荀子). The original text states: 'Blue is taken from indigo, yet it is bluer than indigo' (青，取之于蓝，而青于蓝).
• Original Philosophy: In its original context, Xunzi (荀子) used this metaphor to argue that learning should never stop, as continuous education and effort can allow a person to transcend their innate qualities.
• Full Expression: It is very common to hear the extended version: 青出于蓝而胜于蓝 (qīng chū yú lán ér shèng yú lán). The addition of 胜于蓝 (shèng yú lán) explicitly means 'superior to the indigo,' further emphasizing the student's superiority.
