On one occasion, Fang Haiquan wrote a couplet: "The fertile soil of the heart is inexhaustible." Go to the bamboo and wood art shop and turn its lettering into bamboo couplets in bamboo.

The boss liked the wording of this couplet and said to Haiquan, "Brother, can you tell the calligrapher that I can copy more and sell it to others?"

Fang Haiquan said, "Yes".

The boss said, "You agreed without asking him." .

Fang Haiquan said, "Don't ask him, so teach people to be old." (small)
