TAIPEI -- Chu Chien-huei stretches her arms in a hot tub full of orchid petals on a sunny day at Spring City Resort, a hot spring hotel in Peitou, with her 5-year-old daughter at her side.

"The water is smooth and good for the skin," says the 30-year-old Chu, who is staying at the hotel with her sister.

Nearby, 62-year-old Chung Jin-chang, after soaking in the hot spring, relaxes under a jet of cold spring water spewing from a fountain.
