It can be likened to a rebus, which uses pictures and single letters, or numbers to represent whole words (e.g, "i <3 u" means “I love you”, b4 means before, lol means laugh out loud, etc. ).

这种短信文是由图片、字母或数字的组合来代表某个单词的，感觉像字谜一样。 比如："i <3 u"就代表“我爱你”（中间的<3像是一颗心的形状，代表“爱”），b4就是before（以前）这个单词的缩写形式，而lol则是laugh out loud（大声笑出来）这三个单词的缩写。
