Usually pay attention to life, accumulate materials, and you will be flexible when writing. There are two poems in Zhu's Random Thoughts on Reading. Which two poems are they?

Song Zhu Xi's half-acre square pond opened and the sky was overcast. Ask the canal to be so clear, because there is running water at the source. Note: This poem is inspirational and has a long history and is always new. Half an acre of pond is like a mirror, reflecting the sky and the clouds flashing back and forth. Why is this pond so clear? It turns out that the source of living water is endless! Poetry has profound meaning. Learning is compared to the source of living water. Only by constantly absorbing new knowledge can we make rapid progress.
