Photographer's Note

These snakes from one garden in Ho Chi Minh. They live in concrete pool without water. It 's not dangeros, they are not venomous. In latin it's Elaphe genus -ratsnakes in English.
Ratsnakes are a group of snakes mainly associated with the genus Elaphe, but also having species in the genera Bogerta, Gonyosoma and Sentalis. The majority are found in Eurasia, with the remainder in North America.

Elaphe species can be characterised by slender bodies, heads that have no distinct join to the neck or body, and three (usually) longitudinal stripes, one along the back and one along each side. They are mostly fairly tolerant of a range of temperatures: if anything many of them should be prevented from getting too warm, rather than too cold. Temperament varies according to species: some become incredibly tame and docile (eg Elaphe guttata guttata, the Corn Snake) while others remain intractable and nasty (notably Gonyosoma oxycephalum, the Red-Tailed Rat Snake).

Rat snakes as a group seem to be geared towards the lower end of the temperature gradient, although there are exceptions (ie those found in Mexico and the tropics of SE Asia). Many of the Asian species are found in the cooler parts of the continent (China, Korea, Central Asia, Siberia or Japan) and are subject to cold winters. It is important to note the distribution and origin of any snake that is to be a captive.
