What is the formula for finding things?

Jia Zhen and B Zuo Bingxin Kun, Ding Gan and Wu Kan went to the city gate and lost their money in Geng Ri. The roots can be found in Renzi, Jia Jiyang and B Gengyin, and the C-hearted boy secretly invaded. Ding Ren can't live without his relatives, and the lost goods don't go out. Meridian is on the roadside, and Shen Yin returns to his hometown. Chen Xu's ugly body did not move, and the mystery of heaven and earth was detailed. A has not gone five miles, B Geng has searched a thousand miles among the people, C Xin has searched ten miles, Ding Ren has searched three miles, and Wu Gui is still hiding here, looking for what was lost in Song Zhong.

The formula for finding things

"Jia Xu and B leave Bingxinkun, Ding Gan and Wu Kan are at the gate, the lost property can be found on Geng Day, and the lost property can be found on Gen Day" is to judge which direction the lost property may be. The eight diagrams of Gan, Kan, Gen, Zhen, Xun, Li, Kun and Hui on the eight diagrams of the day after tomorrow start from the northwest, and the clockwise direction indicates eight directions. A and b,

A on Jiazi Day means Jiazi Day, and "B" means B, which corresponds to "A" and "B" in rhyme. Knowing the direction and date, it is clear at a glance to find what was lost that day. For example, if you look for something lost on March 29, 2007, it is "Ren Xuri", which corresponds to rhyme.
