Reading by night light is a description of hard work. Soldier means pick. What do you think, stir up the center of the oil lamp and light it up so as to read and write better? Don't such people study hard? Of course, there is no need to light any oil lamps in today's society, but people who study hard are everywhere, so the word "reading Yi Deng at night" is not aimed at the ancients, but also applies to people in modern society. In order to prepare for the senior high school entrance examination, my deskmate studied at night with the light on and made a panda eye. Do you think it is worth it?
In addition:
Deng Bing: In ancient times, when there was no electric light, people made a wick out of string and put it in kerosene. When the wick continues to burn, it is necessary to continuously remove the burning wick.
Night reading: Reading at night.
