in my climate zone I keep my Fukien Tea outdoors and it gets sun shine for most part of the day. I have it in bonsai soil instead of that broken down soil it came in. It drinks a lot of water and has a good way of telling me it needs more when the top part of the bonsai mix is completely dry and the pot feels significantly lighter compared to when it's full with water.
The other poster is right if you just got it, try to get it used to a sunny spot in your home 1st without moving the bonsai too much. Try to get the watering right by watering so water comes out of drainage holes. You may have to do this multiple times so water is really absorbed by the soil and root system. Some people prefer leaving the whole pot in a pan of water which comes up to the rim of the pot for a few minutes.
Good luck, let us know
