Advantages and disadvantages of SMS

Pro: Words can be used instead of words to avoid unspeakable embarrassment. Can be used for holiday wishes. You can watch it again after use. Short messages can also be used for long-distance contact, which is more affordable. Disadvantages: I have to worry about being peeked after using text messages. SMS costs too much, sometimes 20 cents a word. In short messages, people with poor Chinese skills will not express clearly, which will reverse others' misunderstanding and make jokes.
