Qiáng-shang guà miàn gǔ. Gǔ-shang huà lǎohǔ.
Lǎohǔ zhuāpòle gǔ.
Ná kuài bù lái bǔ,
Bùzhīdào shì bù bǔ gǔ, háishi bù bǔ hǔ.
Which means something like:
On the wall hangs a drum, on which a tiger is painted. The tiger clawed a hole into the drum. Taking a piece of cloth to repair it, I didn’t know whether the cloth was mending the drum or the cloth was mending the tiger.
