The seven kills in the eight characters are extremely aggressive, destructive and despicable, and must be subdued or resolved before they can be used by the Japanese Lord. Liu Ruyi, a numerologist, said that if the uniform of "Seven Killings" is properly solved, it is the easiest to make a fortune. The uniform of the seven kills can be used by the god of food or the wounded official.
Because the seven kills are the stars of violence, advocating force and being aggressive. The god of food is a star of interest, stubborn, inflexible and sometimes even self-righteous. In addition, the god of food and the seven kills are both positive or negative. Same-sex combination has great unity, but it lacks harmony.
Extended data:
The injured official is a star of wisdom and also a villain. When a wounded officer is killed seven times, it is like two villains meeting, one is good at calculation and the other is good at violence. If these two villains are combined, it will be very powerful.
What's more, it's better to kill seven officials, one yin and one yang, than to kill seven, two positives or two negatives. Therefore, it is a good combination for the wounded officer to see the seven kills in the eight characters, and it is also a fame for the wounded officer to kill together.
People who kill officials are not as good at execution as God of Food, but they are more flexible and certainly more scheming than those who kill officials. In particular, people who kill officials together are brave and good at fighting, and are generally experts in writing, but they are eccentric and unpredictable.
