What do the villagers mean by "conflict"?

This is a folk saying with a certain superstitious color. It refers to the zodiac, which means conflict. It is often used for fortune telling and is also found in some calendars. It is used in many ways. For example, marriage depends on whether the zodiac signs conflict, so don't say anything. If there is no conflict, you can say matchmaking. Another fact is that some people like to look at themselves in that direction today or this month, or this year, which is beneficial to their own genus, and that direction conflicts with their own genus, and so on. In rural areas, collision is a big factor when holding some important activities.
