If the boss’s birthday is short of fire, you can hang a picture of a horse in the office, which symbolizes rapid success.
The five elements of the horse belong to fire. People born in spring and winter are all lacking in fire. A horse with fire can make up for the deficiency. Decorative paintings of horses should not be hung in the south, because the hexagram of the horse belongs to heaven, and if it is hung in the south position (the five elements in the south position belong to fire), it will be "burning the heavenly gate". If it is burned by fire, unfavorable things will easily happen. Such as headaches, dizziness, easy coughing, etc., and it is easy for subordinates to be disobedient and prone to frequent disputes.
If the zodiac signs are rat and ox, which are not compatible with horses, it is not appropriate to hang pictures of horses.
