Micro-love letter, just a few dozen words, short and clear, unpretentious. Slowly, love letters are no longer favored by couples who spent two months ago, but that long and old expression makes them obsolete. Recently, the "Three Quotations Reading Contest" initiated by Zhejiang University students has become popular all over the Internet. This idea, born out of Weibo, has been sought after by countless young people on the Internet, and even has a brand-new concept-micro. The key to the spread of micro-love letters from Weibo lies in one word: micro. The meaning of "micro" and "tiny", "Weibo" is "Weibo". The "micro-love letter" gives people the feeling that it is such a "very, very short" love letter, which echoes the significance that this kind of love letter originally originated in Weibo.
