Book boy and its significance: book boy grinds ink, and ink grinds a pulse of ink on book boy. For those who take care of the daily life of scholars and help them sort out the extremely bookish books, murals, Chinese paintings, operas, novels and other forms have been passed down to this day. For example, Mo Yu, a bookboy who strictly investigated San, Jiu Si, a bookboy of Liang Shanbo, and Yan Ming, a bookboy of Baoyu, are all clever children in history.

A bookworm has a close relationship with a scholar. There are musical instruments, chess, books and paintings in the paintings, which are similar to the anecdotes of painting circles and the stories of literati. The image of a very talented person can be described as a favorite figure in a painter's works. In the "Little Hidden Picture in Spring" painted by Zhou Chen in Ming Dynasty, with the help of the teenagers who cleaned outside the house, the interest of floating out of the dust was highlighted, which echoed the hidden words in the title.
