Literature Reference: How deep, how deep the courtyard is, with its clouded windows and misty pavilions always shut. The tips of willows and the calyxes of plum blossoms gradually become distinct. Spring returns to the trees of Moling, but people grow old in the city of Jiankang. How many things I have sighed over the moon and chanted to the wind, yet now in my old age, I have achieved nothing. Who will pity my haggardness and further decline? Lighting the lanterns holds no interest, and walking in the snow brings no joy. Source from Li Qingzhao's 'Linjiangxian·Tingyuan Shen Shen Shen Ji Xu'.
