I have it in my room, maybe I turned on the heater too much?

Hi,
Or maybe it lives outside in the fresh air and humidity. Or maybe it is too wet.
Up to you how you grow it.

Number one, it's winter. Leaves are not forever, and last longer, better, in a good environment. A south or west window is best indoors. What do you have?

It's being treated as evergreen this Winter. The leaves were brand new. South-facing large window, pot right next to it.
My guess is it got too warm. The window sill is always cool and so is the pot. I usually dont heat my room actively. But I turned on the heater too much for a day or two and it mightve gone up to 25°C, I assume the air was quite dry as well.
I saw a video of Peter Chan today reiterating that Chinese elms dont like heat in Winter.
