What does Tatsumi Empty mean in a four-column arrangement?

Among the sixty Jiazi, there are ten Jiazi, Jiayin, Wu Jia, Shen Jia and JOE. However, it was only ten days before Tiangan Jiazi arrived in Guibu, and Ugly Zi went all the way to the Chinese Zodiac, which led to two days more for Tiangan and Twelve Earthly Branches, so there would be two empty deaths, that is, ten days, and Ugly Er was not applied to Ding You in the Reform Movement of 1898. What you said about Tatsumi is empty. If it is a year, then you must have been born within the above ten years. If the sky is empty, you must have been born in heavenly stems and earthly branches in the last ten months. If it's a natural disaster, then you must have been born in the top ten, heavenly stems and earthly branches Day. If it is time and space, then you must have been born at the time of heavenly stems and earthly branches. Under normal circumstances, there are more empty deaths with moon columns.
