The climate and environment in Northeast China are not suitable for mauremys mutica's breeding, because mauremys mutica lives in a warmer climate and a humid environment, and the water temperature needs to be above 25℃ to move and grow normally. The average annual temperature in Northeast China is low, especially in winter. Therefore, if you want to raise mauremys mutica in Northeast China, you may need to pay special attention to heat preservation and moisture preservation to ensure the stability of water temperature and humidity. At the same time, you need to provide enough light to help turtles synthesize vitamin D3, but you also need to pay attention to avoid excessive sunburn. Generally speaking, if you want to raise mullet, I suggest you consider choosing a warmer climate to raise it.
