In his autobiography, the historian of Chinese philosophy Feng You-lan describes the transformation of the old system into the new in the following terms: "It was like someone who was accustomed to the old calendar using the months and days of the new calendar. He would only feel really sure of the day in his mind after matching up the new date to the corresponding month and day of the old calendar."
中國哲學史家馮友蘭在他的自傳《三松堂自序》中，形容新舊制度的改變，「好像習慣於舊曆的人，談到新曆的月日，他總首先把它折合成舊曆的月日，他才覺得心裡清楚。」
