Hello,
For indoor bonsai "indoor display" is much more important.
For the outdoor Bonsai, many growers bring their trees indoors where they are put on display for special occasions but then afterward, they need to go back outside. A good rule to follow is that three days a month indoors is all your Bonsai, regardless of species, will handle.
For the outdoor Bonsai, they simply cannot and should not be grown inside. Bringing them in during the flowering season or to celebrate a party, is fine but if they are kept indoors too long, they will actually become stressed. If you do bring the Bonsai inside, remember that you will need to take extra care when it comes to watering, sunlight, humidity, and so on.
Additionally, once you put the Bonsai in its position, try to leave it alone as much as possible. The more you start to touch and mess with the Bonsai, the more stressed it will be.
