Practice typing, because most people use pinyin to input, so they still need to have a pinyin foundation! From the common fingering practice, I personally suggest starting with English typing practice and getting familiar with the key positions. Those who can't type can operate through the handwriting board, but they must be skilled in practicing key positions.

Understand system operation and switch.

Can use QQ and other communication software, typing communication, voice communication, video communication.

These are just a few parts of the introduction to computers. The main thing is to practice more, have patience and perseverance, and wish you a happy study.
