Once upon a time, there was a poor scholar whose ancestral land was sandwiched between the fields of a landlord. The landlord regarded it as a thorn in his side and wanted to occupy the land, saying it was his. Otherwise, how could the scholar refuse to accept that it was left by his ancestors, and he mainly took the title deed, but the old title deed could not be found, so the landlord sued the county magistrate. Ber Ber la la; Half black and half white; Two pointed heads. " After drawing lots, it is decided that the landlord will do it first. The landlord scratched his fat head with his fat hand and shook his head. Isn't it easy? Layers of cow dung; Ber Ber la la is sheep dung; Half black and half white is chicken shit; The scholar thought for a moment and said, "the layer is the classics;" Mile after mile is full of stars; Half black and half white is the moon; The magistrate appreciated the poem written by the scholar and said to the landlord, "You are full of shit, and you lost. " 。
