What does it mean to use appropriate materials in the almanac?

Marriage in the solar calendar is the marriage custom of the ancient Han nationality and the first of the "six rites". It is said that the man wants to marry the woman, and the man sends a matchmaker to the woman's house to propose marriage with gifts. If the woman is interested, the man will send a matchmaker to formally propose to her family and bring a certain gift, so it is called "accepting talents".

In today's words, "receiving a gift" means getting engaged and giving gifts, and then discussing the wedding date. Therefore, proper acceptance in the yellow calendar refers to a day suitable for holding a wedding ceremony.
