"Never too old to learn" was first put forward by the famous Athenian philosopher Solon.

Its original literal translation was "the older you get, the more you learn", and now it is generally used to describe people who keep learning and learning while they are alive.

When I was young, I studied to enrich myself. When I grow up, I study to go forward bravely after living alone. Learning in old age is to taste life and enjoy family happiness.

Everyone knows this sentence, but very little can be done. Constant learning and constant precipitation are the artistic conception of life.
