There is a seven-character couplet on the pillars on both sides of Santan Yinyue.
Happiness-only filial piety-is it delicious?
Part I: I am silent and filial;
The second part: Tai Tang You Wei is a collection of poems.
The second couplet "Tai Tang" is a soup made without any seasoning, which is used to describe the taste of poems and books that most people find boring.
