Who will the frog jump into the grass and ask?

This is a sentence in a poem "Seclusion": Frog, propped up with a penny, must go east; Unfortunately, there is running water ahead, so we can't have sex there. In this poem, frog is a kind of moral, which represents the poet's imagination and pursuit of freedom and randomness. In the poem, the frog tries to get rid of the shackles, jumps on the grass with the support of bamboo poles, and walks freely to the east. However, an insurmountable running water appeared in front of it and became an obstacle to its progress. Frogs can't reach their destination because they can't cross the water to find what they want to know.
