《汉书·传·王莽传中》
观卦、晋卦值年，占卜告诉人们应当怎么行动，应当在这年二月建寅的初春时节到束部地区巡视，把礼仪程序安排开列出来。 
观晋掌岁，龟策告从，其以此年二月建寅之节东巡狩，具礼仪调度。 
We should observe the Gua and Jin hexagrams. Divination tells us that we should take action and conduct a tour of inspection in the Shubu region in the early spring of the second month after the establishment of Yin. We should also prepare the ceremonies and procedures for this occasion.
