The declaration that Guilin's mountains and waters are the finest under heaven is now inseparable from the city's public identity. The Southern Song official Wang Zhenggong used the line in a poem encouraging examination candidates, linking landscape praise with scholarly ambition.
The poem is associated with Dushu Yan, or Reading Cave, at the foot of Duxiu Peak. Within the surrounding poem, praise of a place also encourages the people gathered there. Its later life as a city slogan grew from this more particular literary setting.
