What does "dog barking" mean in the yellow calendar?

The "dog barking" in the yellow calendar is a superstition and has no scientific basis.

Gregorian calendar, also known as "perpetual calendar", is an almanac used by the people to predict age and good or bad luck. It is the experience summed up by the ancient working people in China in the long-term farming practice, which is used to guide agricultural production.

Therefore, we should treat the Gregorian calendar rationally, not overly superstitious, but with a scientific and objective attitude.
