If your child is sincere, you will be able to teach him the great way. Translation

It is "If a child is sincere, he can teach his son the great way."

If you really think like this, you can teach your son the way to becoming an immortal.

The original sentence comes from Jin Shengtan's "Reading the Sixth Book of Talents", "The Complete Works of Jin Shengtan 3": When I was young, I heard a joke: In the past, a person was extremely poor; He devoted his life to Lu Zu (referring to Lu Dongbin). Feeling his sincerity, he suddenly came to his home and saw his extreme poverty. He felt extremely pity for him. I thought there was something I could do to help, so I stretched out my finger and pointed at the rock in the courtyard, which turned into gold and said, "What do you want?" The man bowed again and said, "I don't want to." Lu Zu was overjoyed and said: If Zi is like this, he can teach his son the great way. The man said: Otherwise, my heart desires your fingers, head and ears. At that time, the servant privately said that this was a solid joke. If it was really Lu Zu, he would definitely point his finger at it. Today's "The Romance of the Western Chamber" is the finger of Lu Zu. The one who gets it points everywhere and turns it into gold.

This paragraph means that I once heard a joke when I was a child: There was a man who was very poor in the past, but he always served Lu Dongbin very devoutly. Lu Dongbin was moved by his sincere heart, and when he saw that he was poor, he I sympathized with him and wanted to help him, so I stretched out my finger and pointed at the big stone in the yard, which turned into gold. Lu Dongbin said to him, do you want to do this? The man bowed to Lu Dongbin and said, "No." Lu Dongbin was very happy and said to him: If you really think like this, I can teach you the way to become an immortal. Unexpectedly, the man said, "That's not it. I just want your finger in my heart." The following comments will not be translated.
