In nature, four-eyed turtles like to live in pits and ditches in mountainous and hilly areas, and often live in dark places, such as under stones and in tree roots. The four-eyed spotted turtle is very timid. Once frightened, it will immediately retract its head, tail, and limbs into its shell or quickly escape. At the end of April every spring, when the water temperature rises to 15℃, it begins to wake up from hibernation and crawl around, but its range of activities is not large. When the water temperature rises to above 18℃, it begins to forage. In the afternoon when the weather is clear, it likes to lie on the shore with its head raised and its limbs stretched out to bask in the sun. At the end of October, when the water temperature drops to 15℃, it begins to hibernate. The hibernation site is chosen in deep water or under a sheltered, sunny cave or haystack on the shore. During hibernation, the head retracts into the shell, and the limbs and tail are exposed, and it is not very sensitive to environmental changes.

The four-eyed spotted turtle has a very diverse diet and a small appetite. It usually likes to eat animal bait the most. In the natural environment, it mainly feeds on small fish, shrimps, and aquatic insects. When food is scarce, it also eats some small wild fruits.

The maturity age of the four-eyed spotted turtle is 4 summers in southern China, 5 summers in eastern China, and longer in northern China. The weight is generally about 500 grams. Mature parent turtles begin to estrus and mate in mid-May every year. Mating is generally carried out in open water or on a quiet shore. During mating, the male turtle first circles around the female turtle or stands in front of the female turtle, facing the female turtle, stretching his head and neck, moving up and down or shaking left and right to prevent the female turtle from crawling. When the female turtle is still, the male turtle will quickly go behind the female turtle and climb onto the back of the female turtle. At this time, the male turtle's forelimbs hook the front edge of the female turtle's carapace for mating. Egg laying begins in mid-May and ends at the end of August. Egg laying is mostly carried out in the sand on the sunny and leeward river banks. Eggs are laid 1-3 times a year, 2-5 eggs each time. After laying, the fertilized eggs will be hatched with the help of the heat of natural sunlight, which generally takes about 70 days.
