How to explain the relationship between the god of food and the official?

Both the god of food and the official are derived from Tian Gan Tong Bian written by Sixty Jiazi, and Xiang Ke refers to their corresponding Tian Gan Xiang Ke. For example, one-day worker C is a god of food and Xin is an official. When C is a fire, it is said that the god of food is an official. For another example, an official who meets B, an official who meets E, and an official who fucks B are the officials of the God of Food. That's the reason.
