How did the name "Old Faithful Spring" come from in Huangshi National Park?

Old faithful spring is a famous geyser in Huangshi National Park. When it was spraying, a few meters thick water column rose and hissed, spraying a lot of hot water at an altitude of 50 to 60 meters, and white smoke rolled like a volcano, which was very spectacular. Because it erupts every 65 minutes on average, it is very trustworthy, so it is called "old faithful spring".
