Yilan County's Yuanshan is packed with visitors everyday, all here for this foot spa service.

These little creatures are doing all the work, free of charge.

Let's check out what these tiny carps are capable of doing.

These people are holding umbrellas and sitting next to the pool, while soaking their feet in it.In fact, it is a water grass garden in Yuanshan township of Yilan.

The pool has iced cold mountain spring water and was intended for water plant growth.

But given the hot weather, the farm owner decided to open the pool to the public, where people are welcomed to soak their feet in the cold mountain spring water for free.

Another surprise is that thousands of tiny carps are raised in the pool, which eat dead skin off one's feet.It's a kind of pedicure.

The service outside would cost at least NT$150.

But here in Yuanshan of Yilan, this is completely free of charge and that has attracted many visitors who come with their families for a comfortable foot spa experience.
