Luan Piao Fengbo Nujiao Guo's poem.
Zou Yizhou has a novel Tadpole, which inscribed a couplet on a pavilion column in northern Henan. The author is Shi Mu, a famous modern calligrapher in China. "Tadpole becomes a point: slug is a headache-it is a good place to point to the whole body."
Jiaonan dialect called tadpoles Guo Kuo Zi, but left a sentence "tadpole fist leaf", although it was not seen with my own eyes.
In Tang Dynasty, Han Yu visited the north of Gulou Peak in Yuelu Mountain. Please forgive me.
(This is similar to a two-part allegorical saying)
There seems to be no statement.
If in doubt, please ask.
