Digging the wall and stealing light, fireflies reflecting snow, cantilever beams and awl ears, working tirelessly, working tirelessly, persevering in research, forgetting to eat and sleep for ten years. Cold window is bitter, studious, Leng Xia is cool in winter, sensitive and studious. Forget to sleep and eat. Every minute counts. Every minute counts. Every night, I dig the wall to get the light. Three wonders of Bian Wei, I can't see the garden. When the cock crows, I wear out the iron inkstone. I study hard and practice hard, and the wind is lazy. Can't sleep at night. I don't have winter and summer snacks, but I'm not tired of log police pillows. I'm not tired of log police pillows. I won't get tired of doing it. I just sit around the clock waiting for it. Take care of the cocoon, work hard, work hard, lie prone on the table, taste the gall, hang the beam, stab the spine, write books behind the house, read books on the moon, read books in the snow, be brave and diligent, guide the awl to stab the spine, steal light and cut corners, read books on salary, and concentrate on it. I dare not concentrate, but I don't know the taste of meat. I don't look at the garden, but I concentrate.
