Editors recommend choosing auspicious calendars.

In the late Qing Dynasty and the Republic of China, Choosing a Lucky Book was often a reference book placed on the bedside desk by scholars and charlatans. Whether it's a wedding, land reclamation, a long trip, issuing city tickets, or cutting clothes, washing your hair, taking a bath, cutting your nails and pedicure, you should go to see "auspicious day".

Choosing a Lucky Calendar (by Liu) focuses on the concept, basic theory, date selection, calendar and other related basic knowledge of auspicious art, so that readers can have a more comprehensive understanding of the theory of auspicious choice.
