First, when I was in primary school, the word I saw the most was "early". Perhaps at that time, influenced by Mr. Lu Xun's text, everyone imitated Mr. Lu Xun and carved an oblique word "algae" on the desk as a spur and supervision for their own study. I remember that the word "jujube" was deeply engraved at that time, so a few years later, you revisited the old place, and a word "jujube" on a shabby desk really brought back many childhood memories.
Second, in middle school, there were many kinds of words engraved on desks. There are some formulas during the exam, which are convenient to use when you need them, and some are simple formulas. Maybe there was no draft paper at that time, so you can look it up directly on the desk. Some ancient poems, some funny cartoons, and some strange evidence left by two people after quarreling, such as "Wang Chunhua is a pain in the ass", are memories of youth.
Third, when I was in high school and college, my classmates were young and budding. Many people carve the name of so-and-so on their desks. At this time, the name is no longer the name of a nuisance or enemy, but more the name of the person they like, sometimes a name, sometimes two names and a heart. In short, everyone likes to write their thoughts on the table. Besides the name, there is a poem and some lyrics.
