I have grown some nice flowery house plant in my balcony in Shanghai.  My problem is winter.  In winter, the temperature would be around 3 degrees over or below zero for about 2-3 months.  I don't have enough room inside the apartment to keep all of them.  So, I locked up the glass windows on the balcony (they built window around what used to be a balcony.) trying to give the flower a "green house" for higher temperature.  I usually ended up with only a few flowerless branches of them when spring come.  Then worked up those remaining branshes to make them turning to to full pots of flowery plant again by summer.  Then as winte came, most dried up or dropped dead again?  Does any of you have any better way?

Then, a few years ago, desperately trying to buy a X-mas gift for the drawing at a friend's home, I bought a small enclosed aquarium tht looked like a wine glass with about 5 small fish inside.  I thought that was a good idea.

Then, as I continued on the way, I changed my mind.  I was afraid that the winner of my drawing prrize might not take good care of the fish and the fish might die quickly.  So, I bought something else and kep the fish in that small enclosed wine glass myself in my living room.

Of course, very soon, the sub zero temperature arrived.  I had to turned off the house heating whenever I go out to work.  I tried a number of things such as keeping them under the electric bult of my reading lamp or keeping them close to the window when the sun shone.  All did not work, so, one after another, they all died within a few weeks.  Do you hve some good trick for the fish for the winter?
