Explanation: Buying a lamp at home is the least urgent task, and if you are a little poor, this item is sold first. Yun Song bought twelve lamps a day, and hung up his children to poetry clouds: I want to see Huatang take care of the wine bottle, and come to accompany me at dusk for no reason. It should be known that it is a matter of things to be replaced, and finally go out early. The ruler of the family can be judged. Yun Song's poetry is ever-changing, and it cannot be rigid, and the pen and tongue, such as harmony and solemnity, are often thrilling and beyond the reach of people.
