Ignorant people will say that the distance is too far, but I don’t think so. Let me give you an example. First, if you first see the person you want to see far away, but he is I didn’t see you, what would you do? A: Will you call out his name and ask him to come over? Secondly, when he is standing in front of you, will you still call him? A: Not only will you not be able to, you will probably say hey, you said you were right to him. Is it better to have more or less language? Also, love has nothing to do with language, because deaf-mute people can also have love and may be happier than us. Someone once asked me, "You are happy when someone loves you." Or are you happy if you love someone? In fact, both of these are wrong, because loving each other is the happiest, so don’t say who speaks less to whom means nothing.
