When will Huai 'an Brazilian tortoise end its hibernation?

My hometown is Jinhu, Huai 'an, and I have several turtles at home. I usually end my hibernation after the lunar new year. It will take some time to be fully awake at the present temperature. When the temperature is 15-25 degrees, it is similar before and after Qingming. My turtle usually ends hibernation at the end of March, but basically didn't eat a few days ago, so don't worry. When the temperature rises completely, they begin to eat.
