The first half is from Xu Zhimo's essay "Cambridge as I Know It": "How many mornings, I braved the cold and walked alone in the frost-covered Woods-listening to birds singing, looking forward to the sunrise, looking for flowers and plants waking up in the soil, and experiencing the most subtle and wonderful spring letter. Ah, that's the new thrush trying its new sound on the endless green branches over there! Ah, this is the first little snowball to earn semi-frozen soil! Ah, isn't this a newcomer nourished by lonely wicker? "
The second half of the sentence comes from Xu Zhimo's poem Du Fu in the Moon. "Looking at the quiet bridge shadow, counting the thin ripples. I leaned against the moss on the stone fence, which cooled my heart. Moon, you dropped out of school. The bride was ashamed and covered her brocade. You stayed here last night. Can you get her to allow you to come tonight? "
