Literature Reference: 弱岁弄词翰，遂叨明主恩。怀章过越邸，建斾守吴门。西圮阴难驻，东臯意尚存。慙逾六百石，愧负五千言。—— 《近于伊川卜山居将命者画图而至欣然有感聊赋此诗兼寄上浙东元相公大夫使求青田胎化鹤》 In my youth, I dabbled in poetry and was graced by the emperor's favor. Bearing credentials, I passed the Yue mansion; holding banners, I guarded the Wu gate. The shadows of the west bank are hard to linger on, while the spirit of Donggao remains. Ashamed of my meager achievements, I feel unworthy of the Five Thousand Words. Source from 'Reflections on Choosing a Mountain Residence near Yichuan'.
