Short paper: short paper, small paper.
Slanted rows: inclined rows. Line means writing.
One more point:
"草" means cursive writing. Lu You was good at cursive writing. From the existing handwriting of Lu You, it can be seen that his cursive writing was sparse, clear and graceful. This sentence is actually an allusion to Zhang Zhi. It is said that Zhang Zhi is good at cursive writing, but he usually writes regular characters. When people asked him why, he replied, "I am in a hurry and have no time to write in cursive." This means that writing cursive script takes too much time, so I have no time to write. The mainland tourists living in Beijing are very bored, so they use cursive writing for entertainment. Because it is the beginning of light rain, it is called "clear window", and "fine milk" is the small white foam on the water when making tea. "Dividing tea" refers to identifying the grade of tea, which here means tasting tea. Writing cursive scripts while having nothing to do, and sipping tea under the sunny window, on the surface, it is a very leisurely and tranquil state, but behind this, there is hidden the poet's infinite emotions and complaints. Lu You has always had the ambition to do something vigorous for the country, but the position of Yanzhou magistrate is not in line with his ambition. What's more, to meet the emperor once, he doesn't know how long he has to wait in the guest house! The country is in troubled times, but the poet is killing time by writing books and drinking tea. It is really boring and sad! So I could no longer suppress the resentment in my heart, and wrote the last two sentences, "Don't sigh in the dust in plain clothes, I will be home as early as the Qingming Festival.
