The old man said it was another day of defeat. Is it a good day?

The old man said that it was another day of defeat, not a good day. In fact, the day of defeat was not just one day, but ten days, namely, Chen Jia, Yi Si, Shen Bing, Dinghai, Wuxu, Jeju, Chen Geng, Xinsi, Renshen and Guihai. These ten days are called heinous days. On such a day, everything is not suitable. In other words, many things are not suitable for this day.
