Quick answerWhat did Shen Zhurang make public in Huyen Khong studies?
According to Trạch vận tân án, he published the Hoán tinh khẩu quyết, called Thế Quái in Thẩm thị Huyền Không học, to supplement the old oral formula that was considered insufficiently clear. He is also recorded as the inventor of the group of xảo số "one qi connected through all nine palaces", comprising 16 cục, about 1/122 of the total 1944 cục. This is the self-account of that line of books, belonging to the interpretive layer of the discipline.
