What does it mean to create twelve characters in a fortune-telling month?

Do you know that 12 zodiac corresponds to 12 earthly branch? Do you know their order? Every month is counted from the date of the establishment of the 24 solar terms, which roughly corresponds to a certain lunar month (there is no fixed date, not a sentence or two). In the first month (at the beginning of the Spring Festival), Yin Hu was built, in February (at the beginning of the Scaring Festival), Mao Rabbit was built, and in December (at the beginning of the Slight Cold Festival), ugly cow was built. Arrange it yourself.
