On the way, when it rains, the slogan "Stay Zhang, Stay Liu" was immediately put up. Original: the cloudy thunder slowly turns to the wild cloud, and the good horse screams and loves the rain. I want to remember that the dragon bell is in the mud, and I want to destroy courage and the king. Poetry: the slogan leaves Zhang and Liu's road as soon as it rains. Poems by Lu Lun in Tang Dynasty.
