My mother can't read Going home this winter vacation, I want to teach her to send text messages. I hope you can give me some advice. How should I teach her?

Texting is easier than writing letters. They are phonetic. It is suggested to focus on teaching Chinese Pinyin, and typos are still non-mainstream.

It was too difficult to learn all the Chinese characters at once, so I gave up when I was impatient. Old people are different from children. Children's brains learn things easily, while old people learn things more difficultly. Be patient and don't set too big a goal.
