由清华简《筮法》卦图、《别卦》易卦的写法看,可确证先秦时筮书卦爻的写法已用两个数字或符号;由《筮法》卦图和四位占法的八卦取象多同于《说卦传》所述八卦取象看,《说卦传》于《筮法》之前当已存在;《筮法》卦图可证四时、五行、八卦相配的情形于先秦已然发生;但如《筮法》及后来《汉书·魏相传》的四时、五行、八卦结构,实际都暴露出《说卦传》的八卦方位与《月令》诸书的五行方位并不能兼容的问题;《筮法》应属战国后期在传统易占基础上形成的更纯粹的占筮书.

The diagram of the trigrams in the “Divinatory Method” （Shifa 筮法） and the inscription of the hexagrams in the “Sixty-four Hexagrams” （Biegua 别卦） on the bamboo slips collected by Tsinghua University can indeed assure us that the lines of a hexa-gram had been written by two numbers or symbols in pre-imperial era of China. As most of the images taken by the diagram and themantic art according to four positions in the “Divinatory Method” are consistent with those mentioned in the “ Discussion of the Tri-grams” （Shuogua zhuan 说卦传）, it can be seen that the latter had come into being earlier than the former. The diagram of the tri-grams in the Shifa demonstrates that the correlation of the eight trigrams with the four seasons and the five agents had been accom-plished in the pre-imperial times. The correlative structure of the four seasons, the five agents, and the eight trigrams in the Shifa andthe “Biography of Wei Xiang” （Wei Xiang zhuan 魏相传） in the Hanshu （History of the Western Han Dynasty） actually exposes theincompatibility between the eight-trigram positions in the Shugua zhuan and the five-agent positions in the “ Monthly Ordinance”（ Yueling 月令）. The “Divinatory Method” should be attributed to a more pure divination manual based on the Changes-oriented man-tic arts.
