今天，我认识了一个三胞胎，它们是己、已和巳，“己”和“已”相信大家早就认识了，那“巳”它叫什么呢？我问了一下字典妈妈，原来它的名字叫si，表示上午九点到十一点，这就是我认识的三胞胎，让我们把它们记住吧！
Today, I know a triplet. They are self, self and already. I believe that we have known each other for a long time. What is the name of "already"? I asked the mother of the dictionary. Its name was Si, which means from 9:00 to 11:00 in the morning. This is the triplets I know. Let's remember them!
