On Jiazi Day, Jiazi's daughter died and her eldest son died. What do you mean?

This is a fortune-telling symbol. Jiazi is heavenly stems and earthly branches, which was used by the ancients to indicate time. For example, in the Sino-Japanese War, Wu Jia refers to the year, and Jiazi Day and Jiazi refer to the time. On Jiazi Day, Jiazi gave birth to women, so it is good to give birth to a daughter, and it is easy to die when giving birth to a son.
