Èr Hào Jǐng — 'Number Two Well' — is a naturally sulphurous thermal spring accessed through a second borehole in a geothermal field in China, the systematic numbering reflecting the engineering approach to managing and presenting the multiple hot spring outlets of an actively developed geothermal resource. China's modern thermal resort industry has increasingly applied systematic borehole drilling to access geothermal water at consistent temperature and flow rates, and spring complexes featuring multiple numbered wells offer visitors a range of thermal bathing options differentiated by mineral composition, temperature, and depth. The spring provides naturally sulphurous mineral water from the second of a series of productive geothermal boreholes.

Insider tip — Er Hao Jing — Second Well — is one of several named spring outlets in the Suao area of Yilan County, where cold-sulfurous and hot-sulfurous springs emerge side by side, a geological rarity. The Suao area sits where the collision zone between the Eurasian and Philippine Sea Plates drives deep geothermal water to the surface along fault lines. The sulfur content gives the water a distinctive milky-white hue when it cools in the bath. Yilan's northeast coast setting means you can soak while listening to the Pacific surf less than two kilometers away.
