From "Two Poems of Bailudong": "I don't know the depth of spring when reading, and an inch of time is an inch of gold. It is not a Taoist who laughs, but Zhou Qing is pursuing it. "

The first sentence "I don't know if spring is deep" means that I concentrate on my studies, and before I know it, spring will soon pass. "Deep spring" refers to the late spring. As can be seen from this poem, the poet concentrates on reading, is nervous and full every day, and completely forgets the time.

Spring is almost over, which was suddenly discovered by the poet inadvertently. This discovery surprised the poet and made him feel a lot. He feels that time flies too fast and there is always not enough time to learn a lot of knowledge.

The second sentence is the feeling of the poet. "One inch of time and one inch of gold" means a very short time. Here gold is used to describe time, which means that time is precious and should be cherished.
