Comment on short messages. Please talk about your opinion.

Can't say it's a kind of injury. As the name implies, SMS is SMS. A short message of 70 Chinese characters, if you want to get to the point, you must express the meaning of the sender concisely. Generally, there are many people who use pinyin to input, and they don't want to change the wrong words, so the pronunciation is the same, because they know that the other party can understand the meaning. An inch of time is an inch of gold. Since the other party can understand, why bother? Unlike writing a composition or an article. You should revise it again and again to see if there are any language mistakes and typos, and try to do your best.
