Literally, this poem seems to express the feelings of visiting spring, but the place to look for fragrance is the Surabaya coast occupied by Jin people when they crossed the Song Dynasty a long time ago. Zhu didn't go north, and of course it was impossible to swim to the spring water on the bank of Surabaya. In fact, the word "Surabaya" in the poem alludes to Confucius, because in the Spring and Autumn Period, Confucius had sung a string of songs between Zhu and Si to teach his disciples. Therefore, the so-called "seeking incense" refers to the way of seeking saints. Boundless Scenery has a vast performance space, which reveals the poet's original intention of seeking the Holy Way through movies. "East wind" is a metaphor for enlightenment, and "colorful" is a metaphor for the richness of Confucianism. The poet compares the sage's way to the spring breeze that pushes the machine and ignites everything. This is actually a philosophical poem by the richest man, which combines reason with interest in the image. It is Zhu's genius to write philosophical poems without revealing traces.
