Longyou Caves: Mystery Solved on the Purpose of These Caves?

Longyou Caves are also known as Longyou Grottos. This mysterious magnificent underground wonder has baffled historians since its' discovery in 1992. It is believed these caves are at least 2,000 years old if not older.
So far no one can explain why and how these unusual caves were built. I have an exciting new theory, which I present here for the 1st time. It perfectly answers important questions. My answer has been hidden in plain sight! I conclude that the Longyou Caves were created by a prehistory civilization with lost ancient technology and for a very practical purpose.
