"An inch of time is worth an inch of gold, but a thousand dollars can't buy an inch of time" can be said to be a well-known motto to persuade people to cherish time. However, some sources of this poem do not mention Wang Zhenbai's poems. The article "Inch Yin" in the new edition of Ci Yuan is quoted from Shu Tong's poem "Send" in the Yuan Dynasty: "Try your best to indulge in the morning, and an inch of time is an inch of gold." In fact, as early as the Tang Dynasty, when Wang Zhenbai was studying in Bailu Cave under the Five Old Peaks in Lushan Mountain, he wrote the famous sentence "One inch of time is one inch of gold".

Reading doesn't know the depth of spring.

An inch of time is an inch of gold.

It's not that Taoist priests make everyone laugh.

In the early years of Zhenyuan, Bo and his brother were involved in Lushan Mountain, and Bo raised deer, which was very tame and often followed, so he was called Mr. Bailu.
