If you stand in the perspective of feng shui, it depends on the orientation of the balcony. What bearing is high and what bearing is low? If it is not a large apartment, you should not consider the influence of Feng Shui, not to mention the gap between the balcony and the living room will not be too big.
If you are worried, I can give you a complete explanation:
If the balcony is higher than the living room, water will be poured in, which is certainly not good, but if water is regarded as wealth, isn't it "money"?
If the balcony is lower than the living room, isn't there another step when people enter the living room? Isn't life and career thriving?
The key is that if the balcony and the living room have a separate threshold, this is the role of hiding and closing the door.
