A few days ago, my father gave me an old book (incomplete volume) for everyone to help me identify it.

This is a Shi Yinben in the early days of the founding of the People's Republic of China: Almanac (also called the Yellow Calendar).

Published in 195 1. (forty years of the Republic of China).

I don't always say, "What you say is the old almanac". In other words, it is "expired and invalid".

Huang also writes about emperors. Because this almanac was issued by the Royal Qin.
