Yuanhai Ziping: There is a formula. Just memorize it by yourself. It should be noted that there are good and bad luck in empty space. The god of joy will die in the air, and the sky will rejoice. The god of fear will die in the air, and worry will turn into joy. .Empty Death: The heavenly stems from Jia to Gui are ten days. In this ten-day cycle, the combination of ten heavenly stems and twelve earthly branches will leave two earthly branches. The two remaining earthly branches are in this period. The middle of ten days belongs to lack, and its deficiency branch is the emptiness branch. Because the combination of stems and branches in each ten-day period starts from A, the stems and branches starting from A find the void at the head of the ten-day period, and the void is also called Liujia void. The eight characters are centered on the Japanese yen, and the voids of the eight characters are divided into ten days of the day. Because the voids are divided by ten days of the day, there are no voids in the daily branches, but there are voids in the year branches, monthly branches, and hour branches. The ten days of Jiazi are empty, Xuhai is empty; the ten days of Jiaxu are empty, Shenyou; the ten days of Jiashen are empty, Wuwei; the ten days of Jiawu are empty, Chensi; the ten days of Jiachen and Xun are empty, Yinmao is empty; Emptiness is not non-existence, but the lack of independence in the five elements due to its own differences. Due to their lack of quality, most of the void branches are unable to affect fate.
