This toad lives in mountainous areas at an altitude of 1800-2100m, often living in streams and their sides. The environment is an agricultural area, where crops such as corn, peas or buckwheat are planted; the woodlands are mostly walnuts, pine forests and broad-leaved trees.

There is a cluster breeding behavior, and male toads have a strong competition for females in courtship behavior. The male toad holds the female toad's chest with its forelimbs, and the pairing behavior lasts about 2-4 days. The eggs are laid in the backwater pond with slow water flow, and the eggs are in the tubular gelatinous belt. Eggs can be laid during the day or night, and the egg-laying process takes about 3-6 hours. A female toad lays 1500-3000 eggs at one time. The eggs and tadpoles develop and grow in the stream water, and the tadpoles complete metamorphosis and land on the shore before the rainy season of the following year.

Breeding season: October, November
