It's noticeably breezy inside Keelung's Behn Shan Wu mining tunnel.

Tourists are appreciating this historic attraction more than usual with its refreshing drop in temperature of 12 degrees Celsius.

The summer temperature can soar up to over 37 degrees Celsius easily.

As the camera crew follow the official into the old mining tunnel, the temperature dropped to 36.1 degrees, and to 35.6 degrees.

In the dark tunnel, the water running down the sides cool off the air.

Three male visitors are taking pictures inside the tunnel while enjoying the cool atmosphere.

The Behn Shan Wu mining tunnel was left behind at the turn of the century.

The tour guide would lead the tourists through the history while they enjoy the breeze from the other end of the tunnel, which lowered the temperature to 24.8 degrees.

Parents are happy to bring their kids to a cool place during summer while allowing the children to learn about history of the old mining industry in Taiwan.
